Comment 6 for bug 1606215

The fix for https://bugs.launchpad.net/tempest/+bug/1600186 has been committed and verified against an env with Tempest cloned from master. So, the tempest.api.compute.volumes.test_attach_volume.AttachVolumeShelveTestJSON.test_attach_detach_volume test case should be re-run with no skipping.
