Public bug reported:
This bug will happen when using libvirt/QEMU and image_type=rbd.
Rescue instance will produce rescue kernel and ramdisk disk in local.
It will also product rescue disk which will saved in ceph by rbd.
When users want to unrescue instance, nova will remove all rescue kernel and
ramdisk disk in local.
But rescue disk which was created in rescue step will still exist.
We can using rbd or rados command to show whether objects was still existed in
pool or not.
For example:
sudo rbd --pool $POOL_NAME ls | grep .rescue
or
sudo rados --pool $POOL_NAME ls | grep .rescue
Why it will happen?
Because of unrescue action will remove local rescue file and lvm disk but it
didn't remove rdb disk.
Therefore we need to add libvirt images_type condition statement which will
remove correct type of disk.
