Regarding your "regex exodus", I recently added something for this. In
another project, I'm setting the regex in a file I keep in the code repo
instead of project-config.
support for DEVSTACK_GATE_SETTINGS in devstack-gate:
usage in a job definition: https://review.openstack.org/190325
a DEVSTACK_GATE_SETTINGS file that sets DEVSTACK_GATE_TEMPEST_REGEX:
It all seems to be working for me, except I still need to tweak my regex
to get the job passing, but at least I can do that without updating
