glusterd: add "volume label" command
This command is necessary when the local disk/filesystem containing a brick
is unexpectedly lost and then recreated. Since 961bc80c, trying to start
the brick will fail because the trusted.glusterfs.volume-id xattr is
missing, and if we can't start it then we can't replace-brick or self-heal
so we're stuck in a permanently degraded state. This command provides a
way to label the empty brick with the proper volume ID so that further
repair actions become possible.
