Subject: [PATCH 281/304] bitrot/glusterd: gluster volume set command for bitrot should not supported

This patch is backport of: http://review.gluster.org/11118

Currently gluster volume set <VOLNAME> bitrot succeeds. gluster volume
set command for bitrot is not supported.
Gluster should only accept gluster volume bitrot <VOLNAME> * commands.
