* Evict inactive peers from `SyncingEngine`
If both halves of the block announce notification stream have been
inactive for 2 minutes, report the peer and disconnect it, allowing
`SyncingEngine` to free up a slot for some other peer that hopefully
is more active.
This needs to be done because the node may falsely believe it has open
connections to peers because the inbound substream can be closed without
any notification and closed outbound substream is noticed only when node
attempts to write to it which may not happen if the node has nothing to
send.

* Attempt to relieve pressure on `mpsc_network_worker`
`SyncingEngine` interacting with `NetworkWorker` can put a lot of strain
on the channel if the number of inbound connections is high. This is
because `SyncingEngine` is notified of each inbound substream which it
then can either accept or reject and this causes a lot of message
exchange on the already busy channel.
Use a direct channel pair between `Protocol` and `SyncingEngine`
to exchange notification events. It is a temporary change to alleviate
the problems caused by syncing being an independent protocol and the
fix will be removed once `NotificationService` is implemented.
* Apply review comments
* fixes
* trigger ci
* Fix tests
Verify that both peers have a connection now that the validation goes
through `SyncingEngine`. Depending on how the tasks are scheduled,
one of them might not have the peer registered in `SyncingEngine` at which
point the test won't make any progress because block announcement received
from an unknown peer is discarded.
Move polling of `ChainSync` at the end of the function so that if a block
announcement causes a block request to be sent, that can be sent in the
same call to `SyncingEngine::poll()`.

`Protocol` is not a reliable source for the information of connected
peers because it doesn't have real-time information of the actual
connectivity state because it's not resposible for accepting/rejecting
connections and gets that information with delay from `SyncinEngine`.
* Move service tests to `client/network/tests`
These tests depend on `sc-network` and `sc-network-sync` so they should
live outside the crate.
* Move some configs from `sc-network-common` to `sc-network`
* Move `NetworkService` traits to `sc-network`
* Move request-responses to `sc-network`
* Remove more stuff
* Remove rest of configs from `sc-network-common` to `sc-network`
* Remove more stuff
* Fix warnings
* Update client/network/src/request_responses.rs

* Move import queue out of `sc-network`
Add supplementary asynchronous API for the import queue which means
it can be run as an independent task and communicated with through
the `ImportQueueService`.
This commit removes removes block and justification imports from
`sc-network` and provides `ChainSync` with a handle to import queue so
it can import blocks and justifications. Polling of the import queue is
moved complete out of `sc-network` and `sc_consensus::Link` is
implemented for `ChainSyncInterfaceHandled` so the import queue
can still influence the syncing process.
* Move stuff to SyncingEngine
* Move `ChainSync` instanation to `SyncingEngine`
Some of the tests have to be rewritten
* Move peer hashmap to `SyncingEngine`
* Let `SyncingEngine` to implement `ChainSyncInterface`
* Introduce `SyncStatusProvider`
* Move `sync_peer_(connected|disconnected)` to `SyncingEngine`
* Implement `SyncEventStream`
Remove `SyncConnected`/`SyncDisconnected` events from
`NetworkEvenStream` and provide those events through
`ChainSyncInterface` instead.
Modify BEEFY/GRANDPA/transactions protocol and `NetworkGossip` to take
`SyncEventStream` object which they listen to for incoming sync peer
events.
* Introduce `ChainSyncInterface`
This interface provides a set of miscellaneous functions that other
subsystems can use to query, for example, the syncing status.
* Move event stream polling to `SyncingEngine`
Subscribe to `NetworkStreamEvent` and poll the incoming notifications
and substream events from `SyncingEngine`.
The code needs refactoring.
* Make `SyncingEngine` into an asynchronous runner
This commits removes the last hard dependency of syncing from
`sc-network` meaning the protocol now lives completely outside of
`sc-network`, ignoring the hardcoded peerset entry which will be
addressed in the future.
Code needs a lot of refactoring.
* Fix warnings
* Code refactoring
* Use `SyncingService` for BEEFY
* Use `SyncingService` for GRANDPA
* Remove call delegation from `NetworkService`
* Remove `ChainSyncService`
* Remove `ChainSync` service tests
They were written for the sole purpose of verifying that `NetworWorker`
continues to function while the calls are being dispatched to
`ChainSync`.
