Deleting snapshot may take time. The current volume API does not allow to delete volumes with snapshots, so if deleting snapshot may take time, a delete request for a parent volume will fail. This sometimes causes functional test failures in slow environments. wait_for_status() checks whether volume status is in error statuses but previously the expected error status was wrong. Cinder API uses lower case as volume status, so it did not work expectedly. Change-Id: I095894ba39f23bf81d71351818d24dbb5ca459fb
