invoked because Ozone snapshot feature is disabled.
[root@jssnap-1 ~]# ozone sh snapshot delete vol1/buck1 snap3
FEATURE_NOT_ENABLED Operation OMSnapshotDeleteRequest.preExecute(..) cannot be 
invoked because Ozone snapshot feature is disabled.
[root@jssnap-1 ~]# ozone sh snapshot snapshotDiff vol1/buck1 snap1 snap3
[root@jssnap-1 ~]# ozone fs -createSnapshot ofs://ozone1/vol1/buck1 snap4
