This uses table.attested_candidate instead of table.get_candidate, because
it's not obvious how to get a BackedCandidate from just a
CommittedCandidateReceipt.

* Do not send messages twice in bitfield distribution

This removes a bug which resulted in sending bitfield messages multiple
times by not checking if we already relayed them. Besides that it also
adds an optimization to not relay a message to a peer that send us
this message.

* Review comments

* Break some lines

Note that these messages are only sometimes actually passed on to the
candidate backing subsystem, with the consequence that it is
unexpectedly frequent that the provisioner fails to create its
provisionable data.

* Switch to wasm-builder 3.0.0

* Fix deterministic wasm build check

when you use `CMD ["/usr/local/bin/polkadot"]` in dockerfile, you don’t need to use `polkadot` while creating a container.

* *: Update authority discovery and remove WorkerConfig

With https://github.com/paritytech/substrate/pull/7545 the authority
discovery module queries and publishes addresses on an exponentially
increasing interval. Doing so should make custom configurations
obsolete, as operations are retried in a timely fashion in the first
minutes.

* Improve collator side of the collator-protocol

This pr improves the collator-protocol implementation of the collator
side. Besides cleaning up code and rewriting it, the following changed:

- Before on `PeerViewChange` we send an advertisment to every peer, now
this only happens for validators.
- It also adds a check that we send an advertisment message only once
for a connected peer.
- If the same validator was part of the current and next group, we
requested to be connected to this validator two times. This is also
fixed now.
- Instead of having only one connection request, we now are being able
to store multiple of them. This is required as we can have multiple
active leafs at any point of time.

* Switch to common `ConnectionRequests`

* Update node/network/collator-protocol/src/collator_side.rs

* use snake_case for log targets

* remove unused continue

* validator_discovery: when disconnecting, use all addresses

* validator_discovery: simplify request revokation

* fix a typo
