This commit introduces a new concept called `NotificationService` which allows Polkadot protocols to communicate with the underlying notification protocol implementation directly, without routing events through `NetworkWorker`. This implies that each protocol has its own service which it uses to communicate with remote peers and that each `NotificationService` is unique with respect to the underlying notification protocol, meaning `NotificationService` for the transaction protocol can only be used to send and receive transaction-related notifications. The `NotificationService` concept introduces two additional benefits: * allow protocols to start using custom handshakes * allow protocols to accept/reject inbound peers Previously the validation of inbound connections was solely the responsibility of `ProtocolController`. This caused issues with light peers and `SyncingEngine` as `ProtocolController` would accept more peers than `SyncingEngine` could accept which caused peers to have differing views of their own states. `SyncingEngine` would reject excess peers but these rejections were not properly communicated to those peers causing them to assume that they were accepted. With `NotificationService`, the local handshake is not sent to remote peer if peer is rejected which allows it to detect that it was rejected. This commit also deprecates the use of `NetworkEventStream` for all notification-related events and going forward only DHT events are provided through `NetworkEventStream`. If protocols wish to follow each other's events, they must introduce additional abtractions, as is done for GRANDPA and transactions protocols by following the syncing protocol through `SyncEventStream`.
