Allows Nomination Pool configuration to be set by a custom origin
instead of root.

In runtimes, we would set this to be `StakingAdmin`, same as for
pallet-staking.

[litep2p](https://github.com/altonen/litep2p) is a libp2p-compatible P2P
networking library. It supports all of the features of `rust-libp2p`
that are currently being utilized by Polkadot SDK.

Compared to `rust-libp2p`, `litep2p` has a quite different architecture
which is why the new `litep2p` network backend is only able to use a
little of the existing code in `sc-network`. The design has been mainly
influenced by how we'd wish to structure our networking-related code in
Polkadot SDK: independent higher-levels protocols directly communicating
with the network over links that support bidirectional backpressure. A
good example would be `NotificationHandle`/`RequestResponseHandle`
abstractions which allow, e.g., `SyncingEngine` to directly communicate
with peers to announce/request blocks.

I've tried running `polkadot --network-backend litep2p` with a few
different peer configurations and there is a noticeable reduction in
networking CPU usage. For high load (`--out-peers 200`), networking CPU
usage goes down from ~110% to ~30% (80 pp) and for normal load
(`--out-peers 40`), the usage goes down from ~55% to ~18% (37 pp).

These should not be taken as final numbers because:

a) there are still some low-hanging optimization fruits, such as
enabling [receive window
auto-tuning](https://github.com/libp2p/rust-yamux/pull/176

), integrating
`Peerset` more closely with `litep2p` or improving memory usage of the
WebSocket transport
b) fixing bugs/instabilities that incorrectly cause `litep2p` to do less
work will increase the networking CPU usage
c) verification in a more diverse set of tests/conditions is needed

Nevertheless, these numbers should give an early estimate for CPU usage
of the new networking backend.

This PR consists of three separate changes:
* introduce a generic `PeerId` (wrapper around `Multihash`) so that we
don't have use `NetworkService::PeerId` in every part of the code that
uses a `PeerId`
* introduce `NetworkBackend` trait, implement it for the libp2p network
stack and make Polkadot SDK generic over `NetworkBackend`
  * implement `NetworkBackend` for litep2p

The new library should be considered experimental which is why
`rust-libp2p` will remain as the default option for the time being. This
PR currently depends on the master branch of `litep2p` but I'll cut a
new release for the library once all review comments have been
addresses.

This MR contains two major changes and some maintenance cleanup.  

## 1. Free Standing Pallet Benchmark Runner

Closes https://github.com/paritytech/polkadot-sdk/issues/3045, depends
on your runtime exposing the `GenesisBuilderApi` (like
https://github.com/paritytech/polkadot-sdk/pull/1492).

Introduces a new binary crate: `frame-omni-bencher`.  
It allows to directly benchmark a WASM blob - without needing a node or
chain spec.

This makes it much easier to generate pallet weights and should allow us
to remove bloaty code from the node.
It should work for all FRAME runtimes that dont use 3rd party host calls
or non `BlakeTwo256` block hashing (basically all polkadot parachains
should work).

It is 100% backwards compatible with the old CLI args, when the `v1`
compatibility command is used. This is done to allow for forwards
compatible addition of new commands.

### Example (full example in the Rust docs)

Installing the CLI:
```sh
cargo install --locked --path substrate/utils/frame/omni-bencher
frame-omni-bencher --help
```

Building the Westend runtime:
```sh
cargo build -p westend-runtime --release --features runtime-benchmarks
```

Benchmarking the runtime:
```sh
frame-omni-bencher v1 benchmark pallet --runtime target/release/wbuild/westend-runtime/westend_runtime.compact.compressed.wasm --all
```

## 2. Building the Benchmark Genesis State in the Runtime

Closes https://github.com/paritytech/polkadot-sdk/issues/2664

This adds `--runtime` and `--genesis-builder=none|runtime|spec`
arguments to the `benchmark pallet` command to make it possible to
generate the genesis storage by the runtime. This can be used with both
the node and the freestanding benchmark runners. It utilizes the new
`GenesisBuilder` RA and depends on having
https://github.com/paritytech/polkadot-sdk/pull/3412

 deployed.

## 3. Simpler args for `PalletCmd::run`

You can do three things here to integrate the changes into your node:
- nothing: old code keeps working as before but emits a deprecated
warning
- delete: remove the pallet benchmarking code from your node and use the
omni-bencher instead
- patch: apply the patch below and keep using as currently. This emits a
deprecated warning at runtime, since it uses the old way to generate a
genesis state, but is the smallest change.

```patch
runner.sync_run(|config| cmd
-    .run::<HashingFor<Block>, ReclaimHostFunctions>(config)
+    .run_with_spec::<HashingFor<Block>, ReclaimHostFunctions>(Some(config.chain_spec))
)
```

## 4. Maintenance Change
- `pallet-nis` get a `BenchmarkSetup` config item to prepare its
counterparty asset.
- Add percent progress print when running benchmarks.
- Dont immediately exit on benchmark error but try to run as many as
possible and print errors last.

Sometimes you need to debug some issues just by the logs and reconstruct
what happened.
In these scenarios it would be nice to know if a block was imported as
best block, and what it parent was.
So here I propose to change the output of the informant to this:

The stream was just used to communicate from the validator the peer
reports back to the gossip engine. Internally the gossip engine just
forwards these reports to the networking engine. So, we can just do this
directly.

The reporting stream was also pumped [in the worker behind the
engine](https://github.com/paritytech/polkadot-sdk/blob/9d6261892814fa27c97881c0321c008d7340b54b/substrate/client/consensus/beefy/src/worker.rs#L939).
This means if there was a lot of data incoming over the engine, the
reporting stream was almost never processed and thus, it could have
started to grow and we have seen issues around this.

This PR adds a check that `max_timeslices > 0` and errors if not. It
also adds a test for this behaviour and cleans up some misleading docs.

The runtime now can provide a number of predefined presets of
`RuntimeGenesisConfig` struct. This presets are intended to be used in
different deployments, e.g.: `local`, `staging`, etc, and should be
included into the corresponding chain-specs.

Having `GenesisConfig` presets in runtime allows to fully decouple node
from runtime types (the problem is described in #1984).

**Summary of changes:**
- The `GenesisBuilder` API was adjusted to enable this functionality
(and provide better naming - #150):
   ```rust
    fn preset_names() -> Vec<PresetId>;
fn get_preset(id: Option<PresetId>) -> Option<serde_json::Value>;
//`None` means default
    fn build_state(value: serde_json::Value);
    pub struct PresetId(Vec<u8>);
   ```

- **Breaking change**: Old `create_default_config` method was removed,
`build_config` was renamed to `build_state`. As a consequence a node
won't be able to interact with genesis config for older runtimes. The
cleanup was made for sake of API simplicity. Also IMO maintaining
compatibility with old API is not so crucial.
- Reference implementation was provided for `substrate-test-runtime` and
`rococo` runtimes. For rococo new
[`genesis_configs_presets`](https://github.com/paritytech/polkadot-sdk/blob/3b41d66b97c5ff0ec4a1989da5ffd8b9f3f588e3/polkadot/runtime/rococo/src/genesis_config_presets.rs#L530)
module was added and is used in `GenesisBuilder`
[_presets-related_](https://github.com/paritytech/polkadot-sdk/blob/3b41d66b97c5ff0ec4a1989da5ffd8b9f3f588e3/polkadot/runtime/rococo/src/lib.rs#L2462-L2485)
methods.

- The `chain-spec-builder` util was also improved and allows to
([_doc_](https://github.com/paritytech/polkadot-sdk/blob/3b41d66b97c5ff0ec4a1989da5ffd8b9f3f588e3/substrate/bin/utils/chain-spec-builder/src/lib.rs#L19)):
   - list presets provided by given runtime (`list-presets`),
- display preset or default config provided by the runtime
(`display-preset`),
   - build chain-spec using named preset (`create ... named-preset`),


- The `ChainSpecBuilder` is extended with
[`with_genesis_config_preset_name`](https://github.com/paritytech/polkadot-sdk/blob/3b41d66b97c5ff0ec4a1989da5ffd8b9f3f588e3/substrate/client/chain-spec/src/chain_spec.rs#L447)

the runtime. Sample usage on the node side

Closes https://github.com/paritytech/polkadot-sdk/issues/2977

The issue appears to stem from the `aquamarine` crate failing to render
diagrams in re-exported crates.

e.g. as raised
[here](https://github.com/paritytech/polkadot-sdk/issues/2977), diagrams
would render at `frame_support::traits::Hooks` but not the re-exported
doc `frame::traits::Hooks`, even if I added `aquamarine` as a `frame`
crate dependency.

To resolve this, I followed advice in
https://github.com/mersinvald/aquamarine/issues/20

 to instead render
mermaid diagrams directly using JS by adding an `after-content.js`.

This PR ensure that the distance between any leaf and the finalized
block is within a reasonable distance.

For a new subscription, the chainHead has to provide all blocks between
the leaves of the chain and the finalized block.
 When the distance between a leaf and the finalized block is large:
 - The tree route is costly to compute
 - We could deliver an unbounded number of blocks (potentially millions)
(For more details see
https://github.com/paritytech/polkadot-sdk/pull/3445#discussion_r1507210283

)

The configuration of the ChainHead is extended with:
- suspend on lagging distance: When the distance between any leaf and
the finalized block is greater than this number, the subscriptions are
suspended for a given duration.
- All active subscriptions are terminated with the `Stop` event, all
blocks are unpinned and data discarded.
- For incoming subscriptions, until the suspended period expires the
subscriptions will immediately receive the `Stop` event.
    - Defaults to 128 blocks
- suspended duration: The amount of time for which subscriptions are
suspended
    - Defaults to 30 seconds

Added `TryFrom<&'a RuntimeString> for &'a str`

migrations: prevent accidentally using unversioned migrations instead of `VersionedMigration` (#3835)

closes #1324 

#### Problem
Currently, it is possible to accidentally use inner unversioned
migration instead of `VersionedMigration` since both implement
`OnRuntimeUpgrade`.

#### Solution

With this change, we make it clear that value of `Inner` is not intended
to be used directly. It is achieved by bounding `Inner` to new trait
`UncheckedOnRuntimeUpgrade`, which has the same interface (except
`unchecked_` prefix) as `OnRuntimeUpgrade`.

#### `try-runtime` functions

Since developers can implement `try-runtime` for `Inner` value in
`VersionedMigration` and have custom logic for it, I added the same
`try-runtime` functions to `UncheckedOnRuntimeUpgrade`. I looked for a
ways to not duplicate functions, but couldn't find anything that doesn't
significantly change the codebase. So I would appreciate If you have any
suggestions to improve this

chainHead: Allow methods to be called from within a single connection context and limit connections (#3481)

This PR ensures that the chainHead RPC class can be called only from
within the same connection context.

The chainHead methods are now registered as raw methods. 
- https://github.com/paritytech/jsonrpsee/pull/1297
The concept of raw methods is introduced in jsonrpsee, which is an async
method that exposes the connection ID:
The raw method doesn't have the concept of a blocking method. Previously
blocking methods are now spawning a blocking task to handle their
blocking (ie DB) access. We spawn the same number of tasks as before,
however we do that explicitly.

Another approach would be implementing a RPC middleware that captures
and decodes the method parameters:
- https://github.com/paritytech/polkadot-sdk/pull/3343
However, that approach is prone to errors since the methods are
hardcoded by name. Performace is affected by the double deserialization
that needs to happen to extract the subscription ID we'd like to limit.
Once from the middleware, and once from the methods itself.

This PR paves the way to implement the chainHead connection limiter:
- https://github.com/paritytech/polkadot-sdk/issues/1505
Registering tokens (subscription ID / operation ID) on the
`RpcConnections` could be extended to return an error when the maximum
number of operations is reached.

While at it, have added an integration-test to ensure that chainHead
methods can be called from within the same connection context.

Before this is merged, a new JsonRPC release should be made to expose
the `raw-methods`:
- [x] Use jsonrpsee from crates io (blocked by:
https://github.com/paritytech/jsonrpsee/pull/1297)

derive-syn-parse v0.2.0 came out recently which (finally) adds support

Upgrading to this will remove many of the places where syn 1x was still
compiling alongside syn 2x in the polkadot-sdk workspace.

This also upgrades `docify` to 0.2.8 which is the version that upgrades
derive-syn-pasre to 0.2.0.

Additionally, this consolidates the `docify` versions in the repo to all
use the latest, and in one case upgrades to the 0.2x syntax where 0.1.x

Related Issue https://github.com/paritytech/polkadot-sdk/issues/3398

This PR makes permissionless withdrawing the default option, giving any
network participant access to claim pool rewards on member's behalf. Of
course, members can still opt out of this by setting a `Permissioned`
claim permission.

Permissionless claiming has been a part of the nomination pool pallet
for around 9 months now, with very limited uptake (~4% of total pool
members). 1.6% of pool members are using `PermissionlessAll`, strongly
suggesting it is not wanted - it is too ambiguous and doesn't provide
guidance to claimers.

Stakers expect rewards to be claimed on their behalf by default - I have
expanded upon this in detail within the [accompanying issue's
discussion](https://github.com/paritytech/polkadot-sdk/issues/3398).
Other protocols have this behaviour, whereby staking rewards are
received without the staker having to take any action. From this
perspective, permissionless claiming is not intuitive for pool members.
As evidence of this, over 150,000 DOT is currently unclaimed on
Polkadot, and is growing at a non-linear rate.
