Subject: Add openshift_openstack role and move tasks there

All the tasks that were previously in playbooks are now under
`roles/openshift_openstack`.

The `openshift-cluster` directory now only contains playbooks that
include tasks from that role. This makes the structure much closer to
that of the AWS provider.
