When rbd is used for ephemeral disks and image storage, make snapshot use ceph directly, and update glance with the new location. In case of failure, it will gracefully fallback to the "generic" snapshot method. This requires changing the typical permissions for the nova ceph user (if using authx) to allow writing to the pool where vm images are stored, and it also requires configuring Glance to provide a v2 endpoint with direct_url support enabled (there are security implications to doing this).
