ZK watches leaks during snapshots

      Description

      When taking snapshot of a table a watcher over /hbase/online-snapshot/abort/snapshot-name is created which is never cleared when the snapshot is successful. If we use snapshots to take backups daily we accumulate a lot of watches.

      Steps to reproduce -
      1) Take snapshot of a table - snapshot 'table_1', 'abc'
      2) Run the following on zk node or alternatively observe zk watches metric
      echo "wchc" | nc localhost 2181
      /hbase/online-snapshot/abort/abc can be found.
