* client/network: Add scaffolding for finality req to use req resp
	#sc

* client/network/src/finality_requests: Remove

* client/network/src/behaviour: Pass request id down to sync

* client/network: Use request response for block requests

* client/network: Move handler logic into *_*_handler.rs

* client/network: Track ongoing finality requests in protocol.rs

* client/network: Remove commented out finalization initialization

* client/network: Add docs for request handlers

* client/network/request_responses: Fix early connection closed error

* client/network/protocol: Fix line length

* client/network/protocol: Disconnect on most request failures

* client/network/protocol: Disconnect peer when oneshot is canceled

* client/network/protocol: Disconnect peer even when connection closed

* client/network/protocol: Remove debugging log line

* client/network/request_response: Use Clone::clone for error

* client/network/request_response: Remove outdated comment

With libp2p v0.33.0 libp2p-request-response properly sends inbound
failures on connections being closed.
