This pull requests splits the block announce processing into two parts.
Into a phase that is called pre-validation that will be async and call
the block announce validator and into a second phase that processes the
result of the pre-validation.

The important change here is that the pre-validation phase is async.
This will be required by Cumulus/parachains. When a parachain announces
a block, it adds the candidate message send by the relay chain as extra
data into the block announcement. To verify this candidate message, the
relay chain parent is required that was used when building this message.
Now it can happen that we first receive the block announcement before
fully importing the relay chain block and this leads to the parachain
block not being imported. By making the pre-validation async, we will be
able to wait for the relay chain block to be imported to verify the
candidate message.

* client/*: Treat protocol name as str and not [u8]

Notification protocol names are in practice always valid utf8 strings.
Instead of treating them as such in the type system, thus far they were
casted to a [u8] at creation time.

With this commit protocol names are instead treated as valid utf8
strings throughout the codebase and passed as `Cow<'static, str>`
instead of `Cow<'static, [u8]>`. Among other things this eliminates the
need for string casting when logging.

* client/network: Don't allocate when protocol name is borrowed

* client/cli/src/config: Warn on low file descriptor limit

Substrate sets the soft file descriptor limit to the hard limit at
startup. In the case of the latter being low already (< 10_000) a
Substrate node under high demand might run into issues e.g. when opening
up new TCP connections or persisting data to the database.

With this commit a warn message is printed to stderr.

… next (#6788)

* frame/authority-discovery: Have authorities() return both current and next

Authority address lookups on the DHT happen periodically (every 10
mintues) and are rather slow (~10 seconds).

In order to smooth the transition period between two sessions, have the
runtime module return both the current as well as the next authority
set. Thereby the client authority module will:

1. Publish its addresses one session in advance.

2. Prefetch the addresses of authorities of the next session in advance.

This edge count is used for weighing, and it is somewhat trivial to review and verify that the current implementation was ignoring `votes16` field of the struct. As reminder, the struct is like this: 
```rust

struct Compact {
  votes1: ... ,
  votes2: ..., 
  ...,
  votes16: ...,
}
```

I already will fix this in #7007, but since it might take a while, this one can go in asap and make it to the very next runtime.

* Refactor sc-network/service metrics.

  1. Aggregate sc-network metrics into a submodule, introducing
  two more sourced metrics to avoid duplicate atomics.

  2. Decouple periodic sc-service network metrics from other
  metrics, so that they can be updated independently.

Extend `sub_libp2p_kbuckets_num_nodes` Prometheus metric to expose the
number of nodes per bucket per Kademlia instance instead of only per
Kademlia instance.

This improves the error message of wasm-builder when the wasm toolchain
isn't installed. Currently we print that the wasm toolchain is not
installed, but the actual problem is that there is a bug in the
packaging in rust. This will now be much easier to debug, by printing
the full error message of the compiler.

* Send import notification always for re-orgs

This pr changes the behavior of sending import notifications. Before we
only send notifications when importing blocks on the tip of the chain or
on similar conditions. However we did not send a notification when we
for example being in a state where we import multiple blocks to catch
up. If we re-org in this process, systems like the transaction pool
would not be notified about this re-org. This means, that we would also
not resubmit transactions of these retracted blocks. This pr fixes this,
by always sending a notification on a re-org.

See
https://github.com/substrate-developer-hub/substrate-node-template/issues/82
for some context about the bug.
