Lldenaurois 2d66b8f256 Dispute Coordinator: Batch queries (#3459)
* disputes: Allow batch queries in dispute-coordinator

This commit moves to batch queries when responding to QueryCandidateVotes
messages. This simplifies the code in the provisioner and dispute-coordinator
by no longer requiring to make use of a FuturesOrdered when awaiting multiple
quries. Instead, the provisioner need only request the batch itself.

* node/approval-voting: Address Feedback to fail on query element missing.

* Address feedback

* Fix implementer's guide

Bastian Köcher 2ea1587e8d Only send one collation per relay parent at a time to validators (#3360)
* Only send one collation per relay parent at a time to validators

This changes the way we are sending collations to validators. Before we
answered every collation request immediatley. Now we only answer one
pov request at a time per relay parent. This should bring down the
bandwidth requirements and should help parachains to include bigger
blocks more easily.

* Guide updates

* Review feedback.

Bastian Köcher 4975521d48 Notify collators about seconded collation (#2430)
* Notify collators about seconded collation

This pr adds functionality to inform a collator that its collation was
seconded by a parachain validator. Before this signed statement was only
gossiped over the validation substream. Now, we explicitly send the
seconded statement to the collator after it was validated successfully.

Besides that it changes the `CollatorFn` to return an optional result
sender that is informed when the build collation was seconded by a
parachain validator.

* Add test

* Make sure we only send `Seconded` statements

* Make sure we only receive valid statements

* Review feedback
