[openstack][cinder] volume revert to snapshot on stein

Hello Stackers, does cinder revert to snapshot works on stein ? The command cinder revert-to-snapshot returns: error: argument <subcommand>: invalid choice: u'revert-to-snapshot' *I also tried using cinder v3 api* post /v3/{project_id}/volumes/{volume_id} /action but it returns : {"itemNotFound": {"message": "The resource could not be found.", "code": 404}} Please, anyone could help me ?
