> As [~mbertozzi] comments on HBASE-16464,  there maybe race condition between SnapshotManager
and SnapshotCleaner.  We should use one lock when create snapshot,  and cleanup should acquire
the lock before take action.
> One method is pass HMaster as param into Cleaner through {{FileCleanerDelegate.getDeletableFiles}},
 suggestions are welcomed.
