Comment 3 for bug 1576729

Will be fixed in https://review.fuel-infra.org/#/c/20123/

This is a new Tempest test case added specifically for https://bugs.launchpad.net/nova/+bug/1570748 which was fixed recently and has not been backported to our downstream branch yet.

Already fixed in Newton and, thus, 10.0 won't be affected.
