[consensus] Add consensus op-level lag metrics It may be useful to see how far behind the leaders each follower is with regard to replicating operations. As such, this patch adds a metric facilitate this. The new metric counts the number of operations behind the leader each peer is. It is updated when a follower receives a request from a leader, and after the peer message queue appends operations.
