While `sp-api-proc-macro` isn't used directly and thus, it should have
the same features enabled as `sp-api`. However, I have seen issues
around `frame-metadata` not being enabled for `sp-api`, but for
`sp-api-proc-macro`. This can be prevented by using the
`frame_metadata_enabled` macro from `sp-api` that ensures we have the
same feature set between both crates.

Extracted to a separate PR as requested here:
https://github.com/paritytech/parity-bridges-common/pull/2873#discussion_r1562459573

As discovered during investigation of
https://github.com/paritytech/polkadot-sdk/issues/3314 and
https://github.com/paritytech/polkadot-sdk/issues/3673 there are active
validators which accidentally might change their network key during
restart, that's not a safe operation when you are in the active set
because of distributed nature of DHT, so the old records would still
exist in the network until they expire 36h, so unless they have a good
reason validators should avoid changing their key when they restart
their nodes.

There is an effort in parallel to improve this situation
https://github.com/paritytech/polkadot-sdk/pull/3786, but those changes
are way more intrusive and will need more rigorous testing, additionally
they will reduce the time to less than 36h, but the propagation won't be
instant anyway, so not changing your network during restart should be
the safest way to run your node, unless you have a really good reason to
change it.

## Proposal
1. Do not auto-generate the network if the network file does not exist
in the provided path. Nodes where the key file does not exist will get
the following error:
```
Error: 
   0: Starting an authorithy without network key in /home/alexggh/.local/share/polkadot/chains/ksmcc3/network/secret_ed25519.
      
       This is not a safe operation because the old identity still lives in the dht for 36 hours.
      
       Because of it your node might suffer from not being properly connected to other nodes for validation purposes.
      
       If it is the first time running your node you could use one of the following methods.
      
       1. Pass --unsafe-force-node-key-generation and make sure you remove it for subsequent node restarts
      
       2. Separetly generate the key with: polkadot key generate-node-key --file <YOUR_PATH_TO_NODE_KEY>
```

2. Add an explicit parameters for nodes that do want to change their
network despite the warnings or if they run the node for the first time.
`--unsafe-force-node-key-generation`

3. For `polkadot key generate-node-key` add two new mutually exclusive
parameters `base_path` and `default_base_path` to help with the key
generation in the same path the polkadot main command would expect it.
 
4. Modify the installation scripts to auto-generate a key in default
path if one was not present already there, this should help with making
the executable work out of the box after an instalation.

## Notes

Nodes that do not have already the key persisted will fail to start
after this change, however I do consider that better than the current
situation where they start but they silently hide that they might not be
properly connected to their peers.

## TODO
- [x] Make sure only nodes that are authorities on producation chains
will be affected by this restrictions.
- [x] Proper PRDOC, to make sure node operators are aware this is
coming.

Changes:
- Add pallet-parameters to Rococo to configure the NIS and preimage
pallet.
- Fix names of expanded dynamic params. Apparently, `to_class_case`
removes suffix `s`, and `Nis` becomes `Ni` 😑

This PR introduces `BlockHashProvider` into `pallet_mmr::Config`
This type is used to get `block_hash` for a given `block_number` rather
than directly using `frame_system::Pallet::block_hash`

The `DefaultBlockHashProvider` uses `frame_system::Pallet::block_hash`
to get the `block_hash`

Closes: #4062

This PR mainly removes `xcm::v3` stuff from `assets-common` to make it
more generic and facilitate the transition to newer XCM versions. Some
of the implementations here used hard-coded `xcm::v3::Location`, but now
it's up to the runtime to configure according to its needs.

Additional/consequent changes:
- `penpal` runtime uses now `xcm::latest::Location` for `pallet_assets`
as `AssetId`, because we don't care about migrations here
- it pretty much simplify xcm-emulator integration tests, where we don't
need now a lots of boilerplate conversions:
      ```
      v3::Location::try_from(...).expect("conversion works")`
      ```
- xcm-emulator tests
- split macro `impl_assets_helpers_for_parachain` to the
`impl_assets_helpers_for_parachain` and
`impl_foreign_assets_helpers_for_parachain` (avoids using hard-coded
`xcm::v3::Location`)

1. The `CustomFmtContext::ContextWithFormatFields` enum arm isn't
actually used and thus we don't need the enum anymore.

2. We don't do anything with most of the normalized metadata that's
created by calling `event.normalized_metadata();` - the `target` we can
get from `event.metadata.target()` and level we can get from
`event.metadata.level()` - let's just call them direct to simplify
things. (`event.metadata()` is just a field call under the hood)

Changelog: No functional changes, might run a tad faster with lots of
logging turned on.

### What's inside

A job, that will take each of the three
[templates](https://github.com/paritytech/polkadot-sdk/tree/master/templates),
yank them out of the monorepo workspace, and push to individual
repositories
([1](https://github.com/paritytech/polkadot-sdk-minimal-template),
[2](https://github.com/paritytech/polkadot-sdk-parachain-template),
[3](https://github.com/paritytech/polkadot-sdk-solochain-template)).

In case the build/test does not succeed, a PR such as [this
one](https://github.com/paritytech-stg/polkadot-sdk-solochain-template/pull/2)
gets created instead.

I'm proposing a manual dispatch trigger for now - so we can test and
iterate faster - and change it to fully automatic triggered by releases
later.

The manual trigger looks like this:

<img width="340px"
src="https://github.com/paritytech/polkadot-sdk/assets/12039224/e87e0fda-23a3-4735-9035-af801e8417fc"/>

### How it works

The job replaces dependencies [referenced by
git](https://github.com/paritytech/polkadot-sdk/blob/d733c77e/templates/minimal/pallets/template/Cargo.toml#L25)
with a reference to released crates using
[psvm](https://github.com/paritytech/psvm).

It creates a new workspace for the template, and adapts what's needed
from the `polkadot-sdk` workspace.

### See the results

The action has been tried out in staging, and the results can be
observed here:

- [minimal
stg](https://github.com/paritytech-stg/polkadot-sdk-minimal-template/)
- [parachain
stg](https://github.com/paritytech-stg/polkadot-sdk-parachain-template/)
- [solochain
stg](https://github.com/paritytech-stg/polkadot-sdk-solochain-template/)

These are based on the `1.9.0` release (using `release-crates-io-v1.9.0`
branch).

# Description

Add `transfer_assets_using()` for transferring assets from local chain
to destination chain using explicit XCM transfer types such as:
- `TransferType::LocalReserve`: transfer assets to sovereign account of
destination chain and forward a notification XCM to `dest` to mint and
deposit reserve-based assets to `beneficiary`.
- `TransferType::DestinationReserve`: burn local assets and forward a
notification to `dest` chain to withdraw the reserve assets from this
chain's sovereign account and deposit them to `beneficiary`.
- `TransferType::RemoteReserve(reserve)`: burn local assets, forward XCM
to `reserve` chain to move reserves from this chain's SA to `dest`
chain's SA, and forward another XCM to `dest` to mint and deposit
reserve-based assets to `beneficiary`. Typically the remote `reserve` is
Asset Hub.
- `TransferType::Teleport`: burn local assets and forward XCM to `dest`
chain to mint/teleport assets and deposit them to `beneficiary`.

By default, an asset's reserve is its origin chain. But sometimes we may
want to explicitly use another chain as reserve (as long as allowed by
runtime `IsReserve` filter).

This is very helpful for transferring assets with multiple configured
reserves (such as Asset Hub ForeignAssets), when the transfer strictly
depends on the used reserve.

E.g. For transferring Foreign Assets over a bridge, Asset Hub must be
used as the reserve location.

# Example usage scenarios

## Transfer bridged ethereum ERC20-tokenX between ecosystem parachains.

ERC20-tokenX is registered on AssetHub as a ForeignAsset by the
Polkadot<>Ethereum bridge (Snowbridge). Its asset_id is something like
`(parents:2, (GlobalConsensus(Ethereum), Address(tokenX_contract)))`.
Its _original_ reserve is Ethereum (only we can't use Ethereum as a
reserve in local transfers); but, since tokenX is also registered on
AssetHub as a ForeignAsset, we can use AssetHub as a reserve.

With this PR we can transfer tokenX from ParaA to ParaB while using
AssetHub as a reserve.

## Transfer AssetHub ForeignAssets between parachains

AssetA created on ParaA but also registered as foreign asset on Asset
Hub. Can use AssetHub as a reserve.

And all of the above can be done while still controlling transfer type
for `fees` so mixing assets in same transfer is supported.

# Tests

Added integration tests for showcasing:
- transferring local (not bridged) assets from parachain over bridge
using local Asset Hub reserve,
- transferring foreign assets from parachain to Asset Hub,
- transferring foreign assets from Asset Hub to parachain,
- transferring foreign assets from parachain to parachain using local
Asset Hub reserve.

Small adjustments which should make understanding what is going on much
easier for future readers.

Initialization is a bit messy, the very least we should do is adding
documentation to make it harder to use wrongly.

I was thinking about calling `request_core_count` right from
`start_sales`, but as explained in the docs, this is not necessarily
what you want.

Completes the removal of `try-runtime-cli` logic from `polkadot-sdk`.

Implements the idea from
https://github.com/paritytech/polkadot-sdk/pull/3899
- Removed latencies
- Number of runs reduced from 50 to 5, according to local runs it's
quite enough
- Network message is always sent in a spawned task, even if latency is
zero. Without it, CPU time sometimes spikes.
- Removed the `testnet` profile because we probably don't need that
debug additions.

After the local tests I can't say that it brings a significant
improvement in the stability of the results. However, I belive it is
worth trying and looking at the results over time.

Currently `subsystem-regression-tests` job fails if the first benchmarks
fail and there is no result for the second benchmark. Also dividing the
job makes the pipeline faster (currently it's a longest job)

This is phase 2 of async backing enablement for the system parachains on
the production networks. ~~It should be merged after
polkadot-fellows/runtimes#228 is enacted. After it is released,~~ all
the system parachain collators should be upgraded, and then we can
proceed with phase 3, which will enable async backing in the runtimes.

UPDATE: Indeed, we don't need to wait for the runtime upgrade enactions.
The lookahead collator handles the transition by itself, so we can
upgrade ASAP.

## Scope of changes

Here, we eliminate the dichotomy of having "generic Aura collators" for
the production system parachains and "lookahead Aura collators" for the
testnet system parachains. Now, all the collators are started as
lookahead ones, preserving the logic of transferring from the shell node
to Aura-enabled collators for the asset hubs. So, indeed, it simplifies
the parachain service logic, which cannot but rejoice.

Closes #4041

Changes:
- Increase cache size and reduce retries.
- Ignore Substrate SE links :(
- Fix broken link.

The plain `people-kusama` and `coretime-kusama` chainspecs were uploaded
at https://github.com/paritytech/polkadot-sdk/pull/3961. Only binaries
with compatible runtime versions can run with plain chainspec. For
example:

One of the latest master builds fails:

```
docker run paritypr/polkadot-parachain-debug:master-216509db --chain coretime-kusama
...
Error: Service(Client(Storage("wasm call error Other: Exported method GenesisBuilder_get_preset is not found"))
```

Master build from 5 days ago:

```

## Changes:

1. Rename:
```

people-kusama.json -> people-kusama-genesis.json
```

2. Generate raw chainspec:

```

## Tests:

New chainspec can run on the latest master build:
