// cephRBDVolumeRename renames a given RBD storage volume
// Note that this usually requires that the image be unmapped under its original
// name, then renamed, and finally will be remapped again. If it is not unmapped
// under its original name and the callers maps it under its new name the image
// will be mapped twice. This will prevent it from being deleted.
