Cleanup unused/deprecated files

Remove / change some places that are long deprecated or no longer
needed:

- openstack-common.conf - was used for pulling code from oslo-incubator,
  but that is dead for at least 8 months already.

- deploy.yaml playbook - declared as deprecated more than a year ago

- enroll.yaml playbook - declared as deprecated more than a year ago

- a task and var in bifrost-test-vm role - deprecated test
  playbooks were removed recently, and their handling in this role is no
  longer needed.
