Westend Collectives migration CI check can be fixed once we have
https://github.com/paritytech/try-runtime-cli/pull/58, will open another
PR once it is available.

- [x] Remove deprecated `DmpQueue` pallet from Rococo Contracts, the
migration is complete
- [x] Fix Asset Hub Rococo storage versions
- [x] Add migration check CI for Asset Hub Rococo and Westend Bridge Hub

The `--relay-chain-rpc-urls` CLI flag has been available for a while
now. We have collators with this running and parachain teams are also
using it. It should be fine now to remove the experimental status.

This PR fixes two things:
- relax `force_default_xcm_version` for testnet system parachains (e.g.
BridgeHubWestend has now 2 and there is no way to change it to 3, so we
need to call `force_xcm_version(3)` for every parachain that it is
connected to, because we send XCMv3 messages)
- add `Storage` item to `PolkadotXcm` pallet definition (now we cannot
see storage items for `pallet_xcm` in PJS)


## TODO

- [ ] when merged open PR to `polkadot-fellows/runtimes` repo

# Description

Sometimes changing file descriptor limits is not allowed, but there is
no need to crash the node if/when this happens. Since `fdlimit`'s author
decided to use panics instead of returning `Result`, we need to catch
it.

# Checklist

- [x] My PR includes a detailed description as outlined in the
"Description" section above
- [ ] My PR follows the [labeling requirements](CONTRIBUTING.md#Process)
of this project (at minimum one label for `T`
  required)
- [ ] I have made corresponding changes to the documentation (if
applicable)
- [ ] I have added tests that prove my fix is effective or that my
feature works (if applicable)

Fix some incorrect doc-comments

The `lazy_static` package does not work well in `no-std`: it requires
`spin_no_std` feature, which also will propagate into `std` if enabled.
This is not what we want.

This PR provides simple address uri parser which allows to get rid of
_regex_ which was used to parse the address uri, what in turns allows to
remove lazy_static.

Three regular expressions
(`SS58_REGEX`,`SECRET_PHRASE_REGEX`,`JUNCTION_REGEX`) were replaced with
the parser which unifies all of them.

The new parser does not support Unicode, it is ASCII only.

- save the state of the BEEFY gadget after processing a finality proof.
We need this in order to avoid skipping blocks.
- avoid reprocessing the old state when not necessary

Addresses a bug caused by
https://github.com/paritytech/polkadot-sdk/pull/1189. The changes are
still not released yet, so would like to push the fix soon so it can go
together with the release of the above PR.

`fast_unstake` checks if a staker is exposed in an era. However, this fn
is still returning whether the staker is exposed based on the old
storage item. This PR fixes that by looking in both old and new exposure
storages.

Also adds some integrity tests for paged exposures.

Adds system parachain configuration and gates the `assign_core` call to
only the Broker system parachain.

New release includes logic to move all jobs to `spot instances`.
Thx!

The versioned migrations are already there in pallet nomination-pools:

https://github.com/paritytech/polkadot-sdk/blob/f6ee4781/substrate/frame/nomination-pools/src/migration.rs#L27-L48

Just updating the kitchensink runtime to point to them.

This is also nice because it points the dev to an example of how to use
`VersionedMigration`.

Westend now successfully updated to `spec: 103000`, we **have to
remove** the session keys migration before the next release as it
doesn't gracefully handle reapplying it.

Since preparation for the merge queues needs more time I'm enabling
zombienet jobs in PRs CI back.

We now check for every requirement of `add_assignment` described in [RFC
5](https://github.com/polkadot-fellows/RFCs/blob/gav-corejam/text/0005-coretime-interface.md).
These are:

- Not more than 100 assignments in a schedule
- Assignment parts add up to 57600 (neither overscheduled nor
underscheduled)
- Starting blocks must be greater than or equal to current block + 10
when schedules are added
- Assignments within an added set must be unique
- Assignments within an added set must be sorted

Adds a function for querying the last runtime upgrade spec version. This
can be useful for when writing runtime level migrations to ensure that
they are not executed multiple times. An example would be a session key
migration.

Refunding surplus happens anyway on xcm_executor::post_process(),
automatically refunding surplus to original_origin at the end of
execution. Since SovereignPaidRemoteExporter doesn't ClearOrigin, it can
simply rely on the automatic mechanism.

Furthermore, RefundSurplus instruction refunds _surplus_. Surplus exists
only as a result of Transact, SetErrorHandler or SetAppendix
instructions, none of which being part of the
SovereignPaidRemoteExporter XCM program. So surplus is always zero here
anyway.

Add collectives and glutton parachain westend runtimes to prepare for
#1737.

The removal of system parachain native runtimes #1737 is blocked until
chainspecs and runtime APIs can be dealt with cleanly (merge of #1256
and follow up PRs).

In the meantime, these additions are ready to be merged to `master`, so
I have separated them out into this PR.

Also marked `bridge-hub-westend` as unimplemented in line with [this
issue](https://github.com/paritytech/parity-bridges-common/issues/2602).

TODO
- [x] add to `command-bot` benchmarks
- [x] add to `command-bot-scripts` benchmarks
- [x] generate weights

The goal of this PR is to migrate Identity deposits from the Relay Chain
to a system parachain.

The problem I want to solve is that `IdentityOf` and `SubsOf` both store
an amount that's held in reserve as a storage deposit. When migrating to
a parachain, we can take a snapshot of the actual `IdentityInfo` and
sub-account mappings, but should migrate (off chain) the `deposit`s to
zero, since the chain (and by extension, accounts) won't have any funds
at genesis.

The good news is that we expect parachain deposits to be significantly
lower (possibly 100x) on the parachain. That is, a deposit of 21 DOT on
the Relay Chain would need 0.21 DOT on a parachain. This PR proposes to
migrate the deposits in the following way:

1. Introduces a new pallet with two extrinsics: 
- `reap_identity`: Has a configurable `ReapOrigin`, which would be set
to `EnsureSigned` on the Relay Chain (i.e. callable by anyone) and
`EnsureRoot` on the parachain (we don't want identities reaped from
there).
- `poke_deposit`: Checks what deposit the pallet holds (at genesis,
zero) and attempts to update the amount based on the calculated deposit
for storage data.
2. `reap_identity` clears all storage data for a `target` account and
unreserves their deposit.
3. A `ReapIdentityHandler` teleports the necessary DOT to the parachain
and calls `poke_deposit`. Since the parachain deposit is much lower, and
was just unreserved, we know we have enough.

One awkwardness I ran into was that the XCMv3 instruction set does not
provide a way for the system to teleport assets without a fee being
deducted on reception. Users shouldn't have to pay a fee for the system
to migrate their info to a more efficient location. So I wrote my own
program and did the `InitiateTeleport` accounting on my own to send a
program with `UnpaidExecution`. Have discussed an
`InitiateUnpaidTeleport` instruction with @franciscoaguirre

 . Obviously
any chain executing this would have to pass a `Barrier` for free
execution.

TODO:

- [x] Confirm People Chain ParaId
- [x] Confirm People Chain deposit rates (determined in
https://github.com/paritytech/polkadot-sdk/pull/2281)
- [x] Add pallet to Westend

Disallow reserve transfers that use teleportable fees if `(origin,
fees)` matches `XcmTeleportFilter`.

Add regression tests for filtering based on `XcmTeleportFilter` for both
`(limited_)reserve_transfer_assets()` and `(limited_)teleport_assets`
extrinsics.

This PR introduces:
- XCM  host functions `xcm_send`, `xcm_execute`
- An Xcm trait into the config. that proxy these functions to to
`pallet_xcm`, or disable their usage by using `()`.
- A mock_network and xcm_test files to test the newly added xcm-related
functions.
