Currently all preparations have same priority and this is not ideal in
all cases. This change should improve the finality time in the context
of on-demand parachains and when `ExecutorParams` are updated on-chain
and a rebuild of all artifacts is required. The desired effect is to
speed up approval and dispute PVF executions which require preparation
and delay backing executions which require preparation.

This PR ensures that broadcast future cleans-up the submitted extrinsic

This effectively cleans-up transactions from the pool when the

The `next_retry_time` gets populated when a request receives an error
timeout or any other error, after thatn next_retry would check all
requests in the queue returns the smallest one, which then gets used to
move the main loop by creating a Delay
```
futures_timer::Delay::new(instant.saturating_duration_since(Instant::now())).await,
```

However when we retry a task for the first time we still keep it in the
queue an mark it as in flight so its next_retry_time would be the oldest
and it would be small than `now`, so the Delay will always triggers, so
that would make the main loop essentially busy wait untill we received a
response for the retry request.

Fix this by excluding the tasks that are already in-flight.

Introduce `touch` call designed to address operational prerequisites
before providing liquidity to a pool.

This function ensures that essential requirements, such as the presence
of the pool's accounts, are fulfilled. It is particularly beneficial in
scenarios where a pool creator removes the pool's accounts without
providing liquidity.

- Moved `substrate/frame/contracts/src/tests/builder.rs` into a pub
test_utils module, so we can use that in the
`pallet-contracts-mock-network` tests
- Refactor xcm tests to use XCM builders, and simplify the use case for
xcm-send

Preparation for https://github.com/paritytech/polkadot-sdk/pull/3935

Changes:
- Add some `default-features = false` for the case that a crate and that
dependency both support nostd builds.
- Shuffle files around of some benchmarking-only crates. These
conditionally disabled the `cfg_attr` for nostd and pulled in libstd.
Example [here](https://github.com/ggwpez/zepter/pull/95

). The actual
logic is moved into a `inner.rs` to preserve nostd capability of the
crate in case the benchmarking feature is disabled.
- Add some `use sp_std::vec` where needed.
- Remove some `optional = true` in cases where it was not optional.
- Removed one superfluous `cfg_attr(not(feature = "std"), no_std..`.

All in all this should be logical no-op.

This PR ensures that the reported pruned blocks are unique.

While at it, ensure that the best block event is properly generated when
the last best block is a fork that will be pruned in the future.

To achieve this, the chainHead keeps a LRU set of reported pruned blocks
to ensure the following are not reported twice:

```bash
	 finalized -> block 1 -> block 2 -> block 3
	
	                      -> block 2 -> block 4 -> block 5
	
	           -> block 1 -> block 2_f -> block 6 -> block 7 -> block 8
```

When block 7 is finalized the branch [block 2; block 3] is reported as
pruned.
When block 8 is finalized the branch [block 2; block 4; block 5] should
be reported as pruned, however block 2 was already reported as pruned at
the previous step.

This is a side-effect of the pruned blocks being reported at level N -
1. For example, if all pruned forks would be reported with the first
encounter (when block 6 is finalized we know that block 3 and block 5
are stale), we would not need the LRU cache.

This PR introduces changes enabling the transfer of coretime regions via
XCM.

TL;DR: There are two primary issues that are resolved in this PR:

1. The `mint` and `burn` functions were not implemented for coretime
regions. These operations are essential for moving assets to and from
the XCM holding register.
2. The transfer of non-fungible assets through XCM was previously
disallowed. This was due to incorrectly benchmarking non-fungible asset
transfers via XCM, which led to assigning it a weight of `Weight::Max`,
effectively preventing its execution.

### `mint_into` and `burn` implementation

This PR addresses the issue with cross-chain transferring regions back
to the Coretime chain. Remote reserve transfers are performed by
withdrawing and depositing the asset to and from the holding registry.
This requires the asset to support burning and minting functionality.

This PR adds burning and minting; however, they work a bit differently
than usual so that the associated region record is not lost when
burning. Instead of removing all the data, burning will set the owner of
the region to `None`, and when minting it back, it will set it to an
actual value. So, when cross-chain transferring, withdrawing into the
registry will remove the region from its original owner, and when
depositing it from the registry, it will set its owner to another
account

This was originally implemented in this PR: #3455, however we decided to
move all of it to this single PR
(https://github.com/paritytech/polkadot-sdk/pull/3455#discussion_r1547324892)

### Fixes made in this PR

- Update the `XcmReserveTransferFilter` on coretime chain since it is
meant as a reserve chain for coretime regions.
- Update the XCM benchmark to use `AssetTransactor` instead of assuming
`pallet-balances` for fungible transfers.
- Update the XCM benchmark to properly measure weight consumption for
nonfungible reserve asset transfers. ATM reserve transfers via the
extrinsic do not work since the weight for it is set to `Weight::max()`.

Will make https://github.com/paritytech/polkadot-sdk/pull/4035 easier to

`LiveAsset` is an error to be returned when an asset is not supposed to
be live.
And `AssetNotLive` is an error to be returned when an asset is supposed
to be live, I don't think frozen qualifies as live.

The first test proves that parachains who were migrated over on a legacy
lease can renew without downtime.

The exception is if their lease expires in period 0 - aka within
`region_length` timeslices after `start_sales` is called. The second
test is designed such that it passes if the issue exists and should be
fixed.
This will require an intervention on Kusama to add these renewals to
storage as it is too tight to schedule a runtime upgrade before the
start_sales call. All leases will still have at least two full regions
of coretime.

This PR ensures the proper logging target (ie `libp2p_tcp` or `beefy`)
is displayed.

The issue has been introduced in:
https://github.com/paritytech/polkadot-sdk/pull/4059, which removes the
normalized metadata of logs.

From
[documentation](https://docs.rs/tracing-log/latest/tracing_log/trait.NormalizeEvent.html#tymethod.normalized_metadata):

> In tracing-log, an Event produced by a log (through
[AsTrace](https://docs.rs/tracing-log/latest/tracing_log/trait.AsTrace.html))
has an hard coded “log” target

>
[normalized_metadata](https://docs.rs/tracing-log/latest/tracing_log/trait.NormalizeEvent.html#tymethod.normalized_metadata):
If this Event comes from a log, this method provides a new normalized
Metadata which has all available attributes from the original log,
including file, line, module_path and target

This has low implications if a version was deployed containing the
mentioned pull request, as we'll lose the ability to distinguish between
log targets.

Added a new step in the action that triggers review bot to stop approval
from new pushes.

This step works in the following way:
- If the **author of the PR**, who **is not** a member of the org,
pushed a new commit then:
- Review-Trigger requests new reviews from the reviewers and fails.

It *does not dismiss reviews*. It simply request them again, but they
will still be available.

This way, if the author changed something in the code, they will still
need to have this latest change approved to stop them from uploading
malicious code.

Part of: https://github.com/paritytech/polkadot-sdk/issues/4107

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.
