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

Closes https://github.com/paritytech/polkadot-sdk/issues/155

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

# 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 PR adjusts the serialized format of the the returned RuntimeVersion
in the rpc-spec-v2 methods. This is done to match the format defined
here:
https://paritytech.github.io/json-rpc-interface-spec/api/chainHead_unstable_follow.html#about-the-runtime

- ##### `apis` field as object
`apis` field of `RuntimeVersion` is now returned as an object, e.g. 
```
"apis": {
      "0xdf6acb689907609b": 3,
      "0x37e397fc7c91f5e4": 1,
}
```
instead of 
```
"apis": [
      ["0xdf6acb689907609b", 3],
      ["0x37e397fc7c91f5e4", 1],
]
```
- ##### removed `stateVersion` and `authoringVersion`
`stateVersion` and `authoringVersion` are no longer returned in the
`RuntimeVersion` JSON Object.

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

### Related Issues

Closes: #1507
Closes: #1146

### 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.

Expand `StorageNoopGuard` to be able to add extra context through a
custom error message. When the guard is triggered it panics with an
error message which can be defaulted, set on construction, or set after
it has been constructed.

Turn `StorageNoopGuard` into struct with `storage_root` and
`error_message` and added `from_error_message` constructor and
`set_error_message` setter.

Also added `new()` aliased to `default()`.

This PR ensures that all storage keys under a prefix are returned by the
`chainHead_storage` method.

Before this PR, the `storage_keys` was used with just the `start_key`.
Before the pagination event was generated, the last reported key
`last_key` was saved internally.
When the pagination is resumed, the `last_key` will serve as the next
`start_key` to the `storage_keys` API.

However, this behavior does not function properly for non-prefixed
storage keys.

Entry keys `a`, `ab`, `abc` share a common prefix and therefore the `ab`
key leads to `abc`.
However, for `a`, `ab`, `aB` and `abc`, the `aB` key does not
immediately lead to `abc`.

To mitigate this, the PR saves the start key of the query, together with
the next pagination key.
Improve testing to ensure we have a key entry that doesn't share the
prefix with the descendant key.

I had quite a few conversions to/from `u64` because these were lacking.

Let me know if others are desirable as well for symmetry.

# Description

We are recently trying to upgrade our Substrate version from
`polkadot-v0.9.43` to `polkadot-v1.0.0` and we noticed a critical issue:
all deployed contracts seem to be experiencing a `CodeNotFound` error.
After a thorough investigation, it appears that the root cause of this
issue lies in the mismatch between the storage alias of `CodeInfoOf<T>`
in the migration and its original definition.

This PR corrects the storage alias to align it with its original
definition

I am uncertain about the proper approach for adding tests to this
change. Would the team consider taking over this PR to bring it to
completion?

I was reading source code and noticed these two places that are no

Small tweak to https://github.com/paritytech/polkadot-sdk/pull/1642 to
incorporate the ideas from
https://github.com/paritytech/polkadot-sdk/issues/247.

I think this is the good middle ground, where we have good rust-docs,
and the RA users will also have some hope.

I hope this also showcases the important message of: **It is really not
that hard to make the examples codes in rust-docs compile, and therefore
remain correct. Please embrace this :)**

It moves the documentation of proc macros to their re-export, such that
can link other items in frame-support. This is a patter that we should
embrace for all of macro docs, and apply in PRs like
https://github.com/paritytech/substrate/pull/13987 as well.

Closes #1372 

This fixes the target directories in the polkadot readme. I verified
manually the Ubuntu based install works on a fresh cloud machine. Build
from source also worked as described.

Since #1304 landed `--dev` also works again (not on v1.1.0 though), so I
would consider the install instructions fixed.

Fixes prometheus server not stopping if there are open connections

Upgrades to docify v0.2.4 which adds support for exporting trait and
