I would bet that this was actually fixed two months ago in upstream tempest by slawek here: https://github.com/openstack/tempest/commit/c5c7ba997eb194e8428bfcb802bfabfdfb5ef5fe
The tempest version on the test machine is 19.0.0-0.20180914114331.8316f96.el7ost.noarch
which was built before that patch existed. I verified the patch was not in the installed python module.
The patch has been backported to OSP13, but OSP14 doesn't seem to have any backports at all and the Source isn't set to an upstream tgz like previous releases, though there is a 19.0.0 upstream tag now.
Since the problem described in this bug report should be
