// cephRBDVolumeMarkDeleted marks an RBD storage volume as being in "zombie"
// state
// An RBD storage volume that is in zombie state is not tracked in LXD's
// database anymore but still needs to be kept around for the sake of any
// dependent storage entities in the storage pool. This usually happens when an
// RBD storage volume has protected snapshots; a scenario most common when
// creating a sparse copy of a container or when LXD updated an image and the
// image still has dependent container clones.
