Release Note

After HBASE-20194, we added 2 parts to master's web page.
One is Peers that shows all replication peers and some of their configurations, like peer id, cluster key, state, bandwidth, and which namespace or table it will replicate.
The other one is replication status of all regionservers, we added a tab to region servers division, then we can check the replication delay of all region servers for any peer. This table shows AgeOfLastShippedOp, SizeOfLogQueue and ReplicationLag for each regionserver and the table is sort by ReplicationLag in descending order. By this way we can easily find the problematic region server. If the replication delay is UNKNOWN, that means this walGroup doesn't start replicate yet and it may get disabled. ReplicationLag will update once this peer start replicate.
