John Mulligan 25a5086184 rbd: fix typo in comment & improve comment consistency 
RBD was misspelled as RDB. While I was there I made the comments
for both constants more consistently worded.

John Mulligan 1e3b9a2cd9 rbd: add an initial set of basic mirroring functions 
Add functions:
* SetMirrorMode implementing rbd_mirror_mode_set
* GetMirrorMode implementing rbd_mirror_mode_get
* MirrorEnable implementing rbd_mirror_image_enable2
* MirrorDisable implementing rbd_mirror_image_disable
* MirrorPromote implementing rbd_mirror_image_promote
* MirrorDemote implementing rbd_mirror_image_demote
* MirrorResync implementing rbd_mirror_image_resync
* MirrorInstanceId implementing rbd_mirror_image_get_instance_id

For now, these mirroring related functions are only supported on octopus
builds. Right now the demand is for snapshot based mirroring, which is
new in octopus. We can always relax this in the future and add the
necessary support for nautilus, for journaling only based mirroring.
