This is separate from the previous patch - it's just the results
of running the script so we can review the two a little independently.
We should probably squash them.

Collections are new. openstacksdk as of now doesn't support python2.
We shouldn't pretend to support python2 either. If you're using
ansible new enough to use collections, you can use python3.
This release of openstacksdk only supports 3.6 and onwards, so
set that as our min.
