A temporary volume can be deleted while it is in use by DELETE API accidentally because its status is `available`. To avoid this deletion, this fix sets a value which doesn't accept deletion to volume status of a temporary volume. When a temporary volume is used for backing up, `backing-up` is set. When a temporary volume is used for reverting a snapshot, `in-use` is set because the volume is attached by a host. Closes-Bug: #1970768 Change-Id: Ib6a2e4d68e532b91161df5245c17ce815f12f935
