John Mulligan 24eeb9512c rbd: add a MirrorImageGlobalStatusIter implementing rbd_mirror_image_global_status_list
This adds the function call in the style of an iterator, as the number
of mirrored images in the entire pool could be large. Tests are
included.

John Mulligan 2be2128e33 rbd: add CreateMirrorPeerBootstrapToken & ImportMirrorPeerBootstrapToken functions
* Add CreateMirrorPeerBootstrapToken implementing rbd_mirror_peer_bootstrap_create
* Add ImportMirrorPeerBootstrapToken implementing rbd_mirror_peer_bootstrap_import

These functions can be used to set up mirroring between pools. Basic tests
included. The tests only verify that functions work, not that they
actually mirror data. That is a job for another day.

John Mulligan 97eefba287 rbd: add SetMirrorSiteName and GetMirrorSiteName functions
* Add SetMirrorSiteName implementing rbd_mirror_site_name_set
* Add GetMirrorSiteName implementing rbd_mirror_site_name_get

These functions are used to set the name of the site (for an entire
cluster) for rbd mirroring purposes. It's a bit strange that it's
part of rdb and not rados, but such is life.

Tests included.

mirroring and the full functionality of GetGlobalMirrorStatus.

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.
