The current code runs k8s-on-openstack's ansible in an ansible
task. This makes debugging failures especially difficult.
Instead, move the prep task to update-system-config, which will
ensure the repo is cloned, and move the post task to its own
playbook. The cinder storage class k8s action can be removed from
this completely as it's handled in the rook playbook.
Then just run the k8s-on-openstack playbook as usual, but without
the cd first so that our normal ansible.cfg works.

The k8s-on-openstack project produces an opinionated kubernetes
that is correctly set up to be integrated with OpenStack. All of the
patches we've submitted to update it for our environment have been
landed upstream, so just consume it directly.
It's possible we might want to take a more hands-on forky approach in
the future, but for now it seems fairly stable.
