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

* Notes.
* Runtime -> RuntimeInfo
* qed in debug assert.
* PolkaErr -> Fault.
* Factor out runtime module into utils.
* Add maybe_authority information to `PeerConnected` event.
We already gather this information in authority discovery, so we might
as well share it with others.
This opens up an easy path to trigger validators differently from normal
nodes, e.g. for prioritization. This change has become more important
now, that we just connect to all validators and therefore just have a
long peer list without any information about those nodes.
* Test fix.
* use compressed blob in candidate-validation
* add some tests for compressed code blobs
* remove CompressedPoV and apply compression in collation-generation
* decompress BlockData before executing
* don't produce oversized collations

* Indentation fix.
* Prepare request-response for PoV fetching.
* Drop old PoV distribution.
* WIP: Fetch PoV directly from backing.
* Backing compiles.
* Runtime access and connection management for PoV distribution.
* Get rid of seemingly dead code.
* Implement PoV fetching.
Backing does not yet use it.
* Don't send `ConnectToValidators` for empty list.
* Even better - no need to check over and over again.
* PoV fetching implemented.
+ Typechecks
+ Should work
Missing:
- Guide
