Release Note:
Add more output for DumpReplicationQueues tool.
1. Show the dead regionservers under replication/rs znode.
2. Make a summary about all the queues that belong to peer has been deleted.

> URL: https://issues.apache.org/jira/browse/HBASE-16947
> Project: HBase
> Issue Type: Improvement
> Components: Replication
> Affects Versions: 2.0.0, 1.4.0
> Reporter: Guanghao Zhang
> Assignee: Guanghao Zhang
> Attachments: HBASE-16947-v1.patch, HBASE-16947.patch

>
> Recently we met too many replication WALs problem in our production cluster.
> We need the DumpReplicationQueues tool to analyze the replication queues info
> in zookeeper. So I backport HBASE-16450 to our branch based 0.98 and did some
> improvements for it.
> 1. Show the dead regionservers under replication/rs znode. When there are too
> many WALs under znode, it can't be atomic transferred to new rs znode. So the
> dead rs znode will be leaved on zookeeper.
> 2. Make a summary about all the queues that belong to peer has been deleted.
> 3. Aggregate all regionservers' size of replication queue. Now the
> regionserver report ReplicationLoad to master, but there were not a aggregate
> metrics for replication.
> 4. Show how many WALs which can not found on hdfs. But the reason (WAL Not
> Found) need more time to dig.
