This LGTM, however we don't have CI exercising your changes against a real openstack. We have yet to port the Magnum CI to github actions - I'd like we do that before merging your PR.

Hey @MrFreezeex, we've recently merged the change to enable CI for Magnum in #2379. Could you rebase this PR on top of master so that we see your change in action before we merge it?

Thanks for the great work, I just did that :D

Meh, this was pointless - we're still not exercising this new code in the acceptance tests. I couldn't get Magnum to deploy a cluster in CI and had to skip the tests that would have exercised this code :-/
Sorry for all the trouble, let's merge your PR as it looks good and the risk it breaks anything is rather low.
