### Summary 

This PR introduces new dispatchables to the treasury pallet, allowing
spends of various asset types. The enhanced features of the treasury
pallet, in conjunction with the asset-rate pallet, are set up and
enabled for Westend and Rococo.

### Westend and Rococo runtimes.

Polkadot/Kusams/Rococo Treasury can accept proposals for `spends` of
various asset kinds by specifying the asset's location and ID.

#### Treasury Instance New Dispatchables:
- `spend(AssetKind, AssetBalance, Beneficiary, Option<ValidFrom>)` -
propose and approve a spend;
- `payout(SpendIndex)` - payout an approved spend or retry a failed
payout
- `check_payment(SpendIndex)` - check the status of a payout;
- `void_spend(SpendIndex)` - void previously approved spend;
> existing spend dispatchable renamed to spend_local

in this context, the `AssetKind` parameter contains the asset's location
and it's corresponding `asset_id`, for example:
`USDT` on `AssetHub`,
``` rust
location = MultiLocation(0, X1(Parachain(1000)))
asset_id = MultiLocation(0, X2(PalletInstance(50), GeneralIndex(1984)))
```

the `Beneficiary` parameter is a `MultiLocation` in the context of the
asset's location, for example
``` rust
// the Fellowship salary pallet's location / account
FellowshipSalaryPallet = MultiLocation(1, X2(Parachain(1001), PalletInstance(64)))
// or custom `AccountId`
Alice = MultiLocation(0, AccountId32(network: None, id: [1,...]))
```

the `AssetBalance` represents the amount of the `AssetKind` to be
transferred to the `Beneficiary`. For permission checks, the asset
amount is converted to the native amount and compared against the
maximum spendable amount determined by the commanding spend origin.

the `spend` dispatchable allows for batching spends with different
`ValidFrom` arguments, enabling milestone-based spending. If the
expectations tied to an approved spend are not met, it is possible to
void the spend later using the `void_spend` dispatchable.

Asset Rate Pallet provides the conversion rate from the `AssetKind` to
the native balance.

#### Asset Rate Instance Dispatchables:
- `create(AssetKind, Rate)` - initialize a conversion rate to the native
balance for the given asset
- `update(AssetKind, Rate)` - update the conversion rate to the native
balance for the given asset
- `remove(AssetKind)` - remove an existing conversion rate to the native
balance for the given asset

the pallet's dispatchables can be executed by the Root or Treasurer
origins.

### Treasury Pallet

Treasury Pallet can accept proposals for `spends` of various asset kinds
and pay them out through the implementation of the `Pay` trait.

New Dispatchables:
- `spend(Config::AssetKind, AssetBalance, Config::Beneficiary,
Option<ValidFrom>)` - propose and approve a spend;
- `payout(SpendIndex)` - payout an approved spend or retry a failed
payout;
- `check_payment(SpendIndex)` - check the status of a payout;
- `void_spend(SpendIndex)` - void previously approved spend;
> existing spend dispatchable renamed to spend_local

The parameters' types of the `spend` dispatchable exposed via the
pallet's `Config` and allows to propose and accept a spend of a certain
amount.

An approved spend can be claimed via the `payout` within the
`Config::SpendPeriod`. Clients provide an implementation of the `Pay`
trait which can pay an asset of the `AssetKind` to the `Beneficiary` in
`AssetBalance` units.

The implementation of the Pay trait might not have an immediate final
payment status, for example if implemented over `XCM` and the actual
transfer happens on a remote chain.

The `check_status` dispatchable can be executed to update the spend's
payment state and retry the `payout` if the payment has failed.

Closes #1767 

Until now the `purge-chain` command would only remove the `full`
subfolder of the db folder. However there is also the `parachains` db
that currently remains and can cause problems on node restart.

Example wiht old code:
```
polkadot purge-chain --database paritydb --base-path /tmp/some-folder
Are you sure to remove "/tmp/some-folder/chains/polkadot/paritydb/full"? [y/N]: y
"/tmp/some-folder/chains/polkadot/paritydb/full" removed.
```
In this case `/tmp/some-folder/chains/polkadot/paritydb/parachains`
would remain and might cause problem on node restart because of version
conflicts as described in #1767. After this PR the whole
`/tmp/some-folder/chains/polkadot/paritydb` folder will be deleted.

This PR removes deprecated CI config files

Applied changes from the [User Update
Guide](https://docs.google.com/document/d/1WQijD3bZTCsudOyPcDvugv659nCa2hEp2b_8eRU0h-Q),
diverging in the node side where service.rs is different for
`polkadot-parachain` than in the parachain template.

## [Updated review bot
version](https://github.com/paritytech/polkadot-sdk/commit/677610ba)

updated version to version `2.0.1` which contains
https://github.com/paritytech/review-bot/pull/90, a fix for the team
members not being fetch in its totality.

## [Updated review-bot.yml minApprovals
convention](https://github.com/paritytech/polkadot-sdk/commit/b1446832)

Renamed `min_approvals` to `minApprovals`. A breaking change in
https://github.com/paritytech/review-bot/pull/86 which was done to
standarize all the cases (so now everything is camelCase)

Since the hash rules of this part of the `pallet_prefix/storage_prefix`
are always fixed, we can put the runtime calculation into compile time.

re:
https://forum.polkadot.network/t/blocknumber-vs-timestamps-should-we-abandon-blocktimes-altogether/4077

This exposes the `LastRelayChainBlockNumber` storage member of
`cumulus-pallet-parachain-system` with a getter and alters the behavior
of this storage item to only be updated in `on_finalize` to ensure a
consistent value throughout `on_initialize` and within transactions.

Parachains, especially with features such as asynchronous backing and
agile coretime, should not use the parachain block number as a clock.
Any feature of Polkadot intended to optimize core utilization and
parachain coretime consumption is likely to worsen this clock as it is
practically applied.

Makes SPs first class citizens along with the relay chains in the
context of our CI runtime upgrade checks.

## Code changes

- Sets missing current storage version in `uniques` pallet
- Adds multisig V1 migration to run where it was missing
- Removes executed migration whos pre/post hooks were failing from
collectives runtime
- Initializes storage versions for SP pallets added after genesis
- Originally I was going to wait for
https://github.com/paritytech/polkadot-sdk/pull/1297 to be merged so
this wouldn't need to be done manually, but it doesn't seem like it'll
be merged any time soon so I've decided to set them manually to unblock
this

## CI changes

- Removed dependency of `westend` runtime upgrades being complete prior
to other ones running. I assume it is supposed to cache the
`try-runtime` build for a performance benefit, but it seems it wasn't
working. Maybe someone from the CI team can look into this or explain
why it needs to be there?

- Adds check-runtime-migration jobs for Parity asset-hubs, bridge-hubs
and contract chains

- Updated VARIABLES to accomodate the `kusama-runtime` package being
renamed to `staging-kusama-runtime` in
https://github.com/paritytech/polkadot-sdk/pull/1241

- Added `EXTRA_ARGS` variable to `check-runtime-migration`, and set
`--no-weight-warnings` to the relay chain runtime upgrade checks (relay
chains don't have weight restrictions).

Closes: https://github.com/paritytech/polkadot-sdk/issues/1718

Co-authored-by: Keith Yeung <[email protected]>

What does this PR do?
- Introduced the TotalValueLocked storage for nomination-pools. 
- introduced a slashing api in mock.rs 
- additional test for tracking a slashing event towards a pool without
sub-pools
- migration for the nomination-pools (V6 to V7) with
`VersionedMigration`

Why are these changes needed?
this is the continuation of the work by @Kianenigma

 in this
[PR](https://github.com/paritytech/substrate/pull/13319)

How were these changes implemented and what do they affect?
- It's an extra StorageValue that's modified whenever funds flow in or
out of staking for any of the `bonded_account` of `BondedPools`
- The `PoolSlashed`event is now emitted even when no `SubPools` are
found

Derive `RuntimeDebug\Eq\PartialEq` but do not bound any generics.

This achieved by using their equivalent no bound versions:
`EqNoBound\PartialEqNoBound\RuntimeDebugNoBound`.

Deriving with `Debug`, `Eq`, and `PartialEq` for the `Debt` and `Credit`
type aliases of `Imbalance` is not feasible due to the `OnDrop` and
`OppositeOnDrop` generic types lacking implementations of the same
traits.

This absence posed challenges in testing and any scenarios that demanded
the traits implementations for the type.

closes https://github.com/paritytech/polkadot-sdk/issues/158.
partially addresses
https://github.com/paritytech/polkadot-sdk/issues/226.

Instead of fragile calculation of current balance by looking at `free
balance - ED`, Nomination Pool now freezes ED in the pool reward account
to restrict an account from going below minimum balance. This also has a
nice side effect that if ED changes, we know how much is the imbalance
in ED frozen in the pool and the current required ED. A pool operator
can diligently top up the pool with the deficit in ED or vice versa,
withdraw the excess they transferred to the pool.

## Notable changes
- New call `adjust_pool_deposit`: Allows to top up the deficit or
withdraw the excess deposited funds to the pool.
- Uses Fungible trait (instead of Currency trait). Since NP was not
doing any locking/reserving previously, no migration is needed for this.
- One time migration of freezing ED from each of the existing pools (not
very PoV friendly but fine for relay chain).

This PR is part of [Sync
2.0](https://github.com/paritytech/polkadot-sdk/issues/534) refactoring
aimed at making `ChainSync` a pure state machine.

Resolves https://github.com/paritytech/polkadot-sdk/issues/501.

# Description
This PR introduces two changes:
- the previous `Tracing` trait has been modified to accept contract
address instead of code hash (seems to be way more convenient)
- a new trait `CallInterceptor` that allows intercepting contract calls;
in particular the default implementation for `()` will just proceed in a
standard way (after compilation optimizations, there will be no
footprint of that); however, implementing type might decide to mock
invocation and return `ExecResult` instead

Note: one might try merging `before_call` and `intercept_call`. However,
IMHO this would be bad, since it would mix two completely different
abstractions - tracing without any effects and actual intervention into
execution process.

This will unblock working on mocking contracts utility in drink and
similar tools (https://github.com/Cardinal-Cryptography/drink/issues/33)

This reverts commit b749ff22 (#1745).

This pull request is removing the Kusama and Polkadot runtime crates. As
still some crates dependent on the runtime crates, this pull request is
doing some more changes.

- It removes the `hostperfcheck` CLI command. This CLI command could
compare the current node against the standard hardware by doing some
checks. Later we added the hardware benchmark feature to Substrate. This
hardware benchmark is running on every node startup and prints a warning
if the current node is too slow. This makes this CLI command a duplicate
that was also depending on the kusama runtime.

- The pull request is removing the emulated integration tests that were
requiring the Kusama or Polkadot runtime crates.

Closes #1671 

Adds a `type_id` function to the `Extension` trait, allowing to properly store an retrieve
boxed `Extensions`.

- ##### removed `stateVersion` and `authoringVersion`
`stateVersion` and `authoringVersion` are no longer returned in the
`RuntimeVersion` JSON Object.

- ##### block index in chain head events as integer

### Testing Done
Adjusted existing tests to make sure data is returned in the correct
format.

This pull request is to fix the output text misalignment of `subkey
inspect` command:

(the `Network ID` line has an extra space at the end, and the `Secret
seed` line lacks a leading space)

```
[btwiuse@railway ~]$ subkey inspect '' | cat -A
Secret Key URI `` is account:$
  Network ID:        substrate $
 Secret seed:       0xfac7959dbfe72f052e5a0c3c8d6530f202b02fd8f9f5ca3580ec8deb7797479e$
  Public key (hex):  0x46ebddef8cd9bb167dc30878d7113b7e168e6f0646beffd77d69d39bad76b47a$
  Account ID:        0x46ebddef8cd9bb167dc30878d7113b7e168e6f0646beffd77d69d39bad76b47a$
  Public key (SS58): 5DfhGyQdFobKM8NsWvEeAKk5EQQgYe9AydgJ7rMB6E1EqRzV$
  SS58 Address:      5DfhGyQdFobKM8NsWvEeAKk5EQQgYe9AydgJ7rMB6E1EqRzV$
```

The output should be in the same YAML-like format as `subkey generate`:

```
[btwiuse@railway ~]$ subkey generate  | cat -A
Secret phrase:       awkward eagle survey resemble novel resist modify memory pistol shed flower run$
  Network ID:        substrate$
  Secret seed:       0x20502f79366325b7dc7620664e8844ae69d441baf6e5b571a57d3b3ff28e9586$
  Public key (hex):  0x468874b9e5b6b77333fa702b9201b924d6834bf956e33e2bbe37d131134ca830$
  Account ID:        0x468874b9e5b6b77333fa702b9201b924d6834bf956e33e2bbe37d131134ca830$
  Public key (SS58): 5DfBkAMg5xQmsePFr3BWLZm99smiNyy9axWSgembvFgDKh9v$
  SS58 Address:      5DfBkAMg5xQmsePFr3BWLZm99smiNyy9axWSgembvFgDKh9v$
```

This change will fix `subkey` as well as all binaries that embed it as
the `key` subcommand, for example: `substrate key`, `polkadot key`, etc.

The PR exposes the `rpc_methods` name in the `rpc_methods` response.
This feature is useful for servers that only forward requests to methods
that are reported by the `rpc_methods`.

Jsonrpsee exposes the available methods registered so far. Registering
the `rpc_methods` requires a closure that already stores the result. As
such, the `rpc_methods` method name is manually added to the available
methods.

Closes: https://github.com/paritytech/polkadot-sdk/issues/1627

[`RococoGenesisExt`](https://github.com/paritytech/polkadot-sdk/blob/a414ea75

/polkadot/node/service/src/chain_spec.rs#L152-L171)
is removed. It was the hack to allow overwriting
`EpochDurationInBlocks`. Removal of `RococGenesisExt` prevents from
manipulating the state to change the runtime constants.

Changes:
- Environment variable which controls the `time::EpochDurationInBlocks`
value was added: `ROCOCO_EPOCH_DURATION` (epoch duration will be set to
the value of env),
- `10,100,600` versions of rococo-runtime are built in CI and put into `polkadot-debug` docker image.

`rococo-runtime` building examples:
- to build runtime for `versi_staging_testnet` which had
EpochDurationInBlocks set to 100:
  ```
ROCOCO_EPOCH_DURATION=100 cargo build --features=fast-runtime -p
rococo-runtime
  ```
- to build runtime for `wococo_development`
  ```
ROCOCO_EPOCH_DURATION=10 cargo build --features=fast-runtime -p
rococo-runtime
  ```
- to build `versi-staging` chain spec:
  ```
ROCOCO_EPOCH_DURATION=100 cargo run -p polkadot --features=fast-runtime
-- build-spec --chain versi-staging --raw
  ```
- to build `wococo-dev` chain spec:
  ```
ROCOCO_EPOCH_DURATION=10 cargo run -p polkadot --features=fast-runtime
-- build-spec --chain wococo-dev --raw
  ```

It is also possible to change the epoch duration by replacing the `code` field in the chain spec with the hex dump of pre-built runtime wasm blob (because the epoch duration is hard-coded into wasm blob).

Last week we experienced a governance attack.
Surprisingly, there was no upper limit on the tip amount.

Due to the mechanism of pallet-fragment-election, the council members
will be refreshed immediately. Attacker is easy to control the council
and give a large tip amount.

Add missing events for pallet-bounties

Created a Github Action that uses the [Review-Bot
app](https://github.com/paritytech/review-bot) to require more fine
tuned requirements to review pull requests before allowing the PR to be
merged.

This uses
[`pull_request_target`](https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#pull_request_target)
for the event, not `pull_request`. This is a security measure so that an
attacker doesn’t have access to the secrets.

All the rules have been copied from the original
`.github/pr-custom-review.yml` file.

I want to clarify, this particular commit is **not intended to replace
PRCR yet**.

# Advantages it brings over `PRCR`

Most of the features available in `PRCR` have been duplicated and
enhanced. For a complete detailed write up, please see:
- paritytech/pr-custom-review#114 -> Proposal for the rewrite
- [Review Bot
Documentation](https://github.com/paritytech/review-bot/blob/main/README.md)

The most important features are:
- `include` and `exclude` fields now accept an array, making it easier
to read the regular expressions.
- Ability to skip a rule
- We can set that PRs coming from a particular user or team will cause
the rule to be skipped.
- This is used in the `Audit rule`, which was requested by
@the-right-joyce.
  - This resolves paritytech/pr-custom-review#136
- Ability to request fellows instead of teams
- As requested in polkadot-fellows/runtimes#7, this bot has the ability
to request fellows by rank instead of users.
- We currently have polkadot-fellows/runtimes#31 which is using that
feature.

Aside from all the rules available in `PRCR` I have added a particular
rule to lock the review-bot files and require a review from the
`locks-review` team, the @paritytech/ci team and the
@paritytech/opstooling team to ensure that the file has been written
correctly.

## Next steps

The next steps will consist on paritytech/review-bot#53, once this issue
has been resolved, and `review-bot` has worked without any issues on
this repository for a while, we will upgrade it to be able to fully
replace `PRCR`.

Update the HRMP pallet to use field names for Event variants to improve
metadata for a better client experience.
Event variants are now structs instead of unnamed tuples.

Partially implements Substrate issue
[9903](https://github.com/paritytech/substrate/issues/9903) which
doesn't appear to have been moved to the monorepo.

Follow-up to #1543.
