---------------------------------------------------------------------------

Tested upgrade scenarios before and after the patch.
1) Without patch started two servers and inserted some data.  Ensure replication was on between
these two servers.  Read back the data from the peer cluster.  Data was found.
2) Stopped the parent cluster region server and master.
3) Applied the patch on the parent cluster. 
4) Read back the data from both the clusters.  
5) Inserted new data in the parent cluster. 
6) Read back the data from the peer cluster.  New data was found.
7) Stopped the peer cluster -both master and region server.
8) Applied the patch on the peer cluster.
9) Read back the data from peer cluster.
10) Inserted new data from the parent cluster.
11) Read back the data from the peer cluster. New data was found.

> ReplicationSource tails the logs for each peer. HBASE-11367 introduces ReplicationEndpoint
which is customizable per peer. ReplicationEndpoint is run in the same RS process and instantiated
per replication peer per region server. Implementations of this interface handle the actual
shipping of WAL edits to the remote cluster.
> This issue is for backporting HBASE-11367 to 0.98.
