Bug description:
  When snapshots are stored in rbd, but the rados backend does not
  actually server the snapshot anymore (because it was for example
  deleted behind's cinder back), its not possible to remove the snapshot
  information from cinder anymore. because it does not handle the
  rbd.ImageNotFound exception raised by the rbd bindings.  every attempt
  will end up in "error_deleting".
