Previously, it was only possible to retry the same request on a
different protocol name that had the exact same binary payloads.
Introduce a way of trying a different request on a different protocol if
the first one fails with Unsupported protocol.
This helps with adding new req-response versions in polkadot while
preserving compatibility with unupgraded nodes.
The way req-response protocols were bumped previously was that they were
bundled with some other notifications protocol upgrade, like for async
backing (but that is more complicated, especially if the feature does
not require any changes to a notifications protocol). Will be needed for
implementing https://github.com/polkadot-fellows/RFCs/pull/47
TODO:
- [x] add tests
- [x] add guidance docs in polkadot about req-response protocol
versioning
We currently use a bit of a hack in `.cargo/config` to make sure that
clippy isn't too annoying by specifying the list of lints.
There is now a stable way to define lints for a workspace. The only down
side is that every crate seems to have to opt into this so there's a
*few* files modified in this PR.
Dependencies:
- [x] PR that upgrades CI to use rust 1.74 is merged.

* kusama: update transaction version
* Bump spec_version to 9330

* Change best effort queue behaviour in `dispute-coordinator`
Use the same type of queue (`BTreeMap<CandidateComparator,
ParticipationRequest>`) for best effort and priority in
`dispute-coordinator`.
Rework `CandidateComparator` to handle unavailable parent
block numbers.
Best effort queue will order disputes the same way as priority does - by
parent's block height. Disputes on candidates for which the parent's
block number can't be obtained will be treated with the lowest priority.
* Fix tests: Handle `ChainApiMessage::BlockNumber` in `handle_sync_queries`
* Some tests are deadlocking on sending messages via overseer so change `SingleItemSink`to `mpsc::Sender` with a buffer of 1
