This continues progress towards being able to split the rpcserver into a

It moves the rpcserverSyncManager interface to the internal package as
the SyncManager interface so it becomes rpcserver.SyncManager and

This continues progress towards being able to split the rpcserver into a
separate internal package.
It moves the rpcserverConnManager interface to the internal package as
the ConnManager interface so it becomes rpcserver.ConnManager and
updates the code to use the moved interface.
This is the first of a series of commits that aims to make progress

It consists of creating the package, moving the rpcserverPeer interface
