Description

HBASE-15507 introduced an update_peer_config method to allow online changes to replication config. It depended on HBASE-11393, which so far exists only in master and can only be in 2.0 and above because of some incompatible changes to replication peer config serialization.

To get this in branch-1 will require two things:
1. Port the PeerConfigTracker in HBASE-11393 to branch-1 without taking the incompatible tableCF serialization changes.
2. Port HBASE-15507's logic on top of this.
