[openstack-dev] [cross-project][infra][keystone] Moving towards a Identity v3-only on Devstack - Next Steps

We just had to revert another v3 "fix" because it wasn't verified to
work correctly in the gate - https://review.openstack.org/#/c/315631/
While I realize project-config patches are harder to test, you can do so
with a bogus devstack-gate change that has the same impact in some cases
(like the case above).
I think the important bit on moving forward is that every patch here
which might be disruptive has some manual verification about it working
posted in review by v3 team members before we approve them.
I also think we need to largely stay non voting on the v3 only job until
we're quite confident that the vast majority of things are flipped over
(for instance there remains an issue in nova <=> ironic communication
with v3 last time I looked). That allows us to fix things faster because
we don't wedge some slice of the projects in a gate failure.
