Its done! Except for all the work to make jobs run properly. Early today
(PDT) we converted everything over to our auto generated Zuulv3 config.
Since then we've been working to address problems in job configs.

These problems include:
    Missing inclusion of the requirements repo for constraints in some
    Configuration of python35 unittest jobs in some cases
    Use of sudo checking not working properly
    Multinode jobs not having multinode nodesets

Known issues we will continue to work on:
    Multinode devstack and grenade jobs are not working quite right
    Releasenote jobs not working due to use of origin/ refs in git
    It looks like we may not have job branch exclusions in place for all
    The zuul-cloner shim may not work in all cases. We are tracking down
    and fixing the broken corner cases.

Keep in mind that with things in flux, there is a good chance that
changes enqueued to the gate will fail. It is a good idea to check
recent check queue results before approving changes.

I don't think we've found any deal breaker problems at this point. I am
sure there are many more than I have listed above. Please feel free to
ask us about any errors. For the adventurous, fixing problems is likely
a great way to get familiar with the new system. You'll want to start by
fixing errors in openstack-infra/openstack-zuul-jobs/playbooks/legacy.
Once that stabilizes the next step is writing native job configs within
your project tree. Documentation can be found at
https://docs.openstack.org/infra/manual/zuulv3.html. I expect we'll
spend the next few days ironing out the transition.

Thank you for your patience,
