* Fix merge.
* 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.

Max PoV size for rococo is around 50Meg, compression ratio is about 3.4.
With 30 Meg we should be fine, even with crypto kitties in the PoV.

* 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

* Implement `Debug` manually for CandidateHash
This will make candidate hashes printed consistently without the
`CandidateHash(` and `)` decorations.
* Do not print CompressedPov's guts
It can be overwhelming. Better just use the size.
* Log when candidate is generated
* Print para_id and candidate_hash upon receiving a collation
* Move NetworkBridgeEvent to subsystem::messages.
It is not protocol related at all, it is in fact only part of the
subsystem communication as it gets wrapped into messages of each
subsystem.
* Request/response infrastructure is taking shape.
WIP: Does not compile.
* Multiplexer variant not supported by Rusts type system.
* request_response::request type checks.
* Cleanup.
* Minor fixes for request_response.
* Implement request sending + move multiplexer.
Request multiplexer is moved to bridge, as there the implementation is
more straight forward as we can specialize on `AllMessages` for the
multiplexing target.
Sending of requests is mostly complete, apart from a few `From`
instances. Receiving is also almost done, initializtion needs to be
fixed and the multiplexer needs to be invoked.
* Remove obsolete multiplexer.
* Initialize bridge with multiplexer.
* Finish generic request sending/receiving.
Subsystems are now able to receive and send requests and responses via
the overseer.
* Doc update.
* Fixes.
* Link issue for not yet implemented code.
* Fixes suggested by @ordian - thanks!
- start encoding at 0
- don't crash on zero protocols
- don't panic on not yet implemented request handling
* Update node/network/protocol/src/request_response/v1.rs
Use index 0 instead of 1.

* Compress the PoV block before sending it over the network
This pr changes the way we send PoV blocks over the network. We now
compress the PoV block before it is send over the network. This should
reduce the size significant for PoVs which contain the runtime WASM for
example.

* Minor refactorings in the process of #2177
By having everything peer set related depend directly on the enum the
code becomes more clear and it is also straight forward to add more
peersets/protocols as the compiler will complain if you forget to
implement parts of it.
* Add peer set infos on startup properly
For feature real_overseer.
+ Fixes from review. Thanks @coriolinus and @ordian!
* More structure in network-bridge
Some changes, which would have helped me in groking the code faster.
Entry points/public types more to the top. Factored out implementation
in their own files, to clear up the top-level view.
* Get rid of local ProtocolName type definition.
Does not add much at this level.
* Fix tests + import cleanup.
* Make spaces tabs.
* Clarify what correct parameters to send_message are
* Be more less vague in docs of send_message.
* Apply suggestions from code review

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
