I think this is same as HDFS-3862 right?

> With QuorumJournalManager, it's not important for the ZKFCs to perform any fencing. We
currently workaround this by setting the fencer to /bin/true, but the ZKFC still does things
like create "breadcrumb znodes", etc. It would be simpler to add a config to disable fencing,
and then the ZKFC's job would be simpler
