Description of change
Extracts our sync checker to a service, and uses that service in the BroadcastStage of the Network pipeline.
This is required because if you get all your new transactions from 1 neighbour, and have 1 other neighbour which doesnt have the transaction you need, there is no chance of syncing.
If that second neighbour sends you a very low amount of new transactions(compared to the other neighbour) you will still sync, but very slow.
This has been introduced due to our removal of "ping pong" in #1745
