[replication] Source shouldn't update ZK if it didn't progress
--------------------------------------------------------------

                 Key: HBASE-4499
                 URL: https://issues.apache.org/jira/browse/HBASE-4499
             Project: HBase
          Issue Type: Improvement
    Affects Versions: 0.90.4
            Reporter: Jean-Daniel Cryans
            Priority: Minor
             Fix For: 0.92.0


A relatively minor optimization to be done in ReplicationSource, currently it calls ReplicationSourceManager.logPositionAndCleanOldLogs
whether it made progress or not, generating more load on ZK than necessary. The last position
should be kept around so that we can compare.
