Subject: aws terminate playbook improvements

- Reduce duplication in terminate playbooks between openshift-master and
  openshift-node (they both now just include playbooks/aws/terminate.yml
- update openshift-cluster terminate playbook to include the new shared
  terminate playbook, also delete all cluster hosts at once instead of
  treating masters and nodes differently.
- remove env, host-type and env-host-type tags from instance before
  terminating (since most users can't terminate, we are mostly just renaming
  instances to -terminate and stopping them, so this prevents "terminated" hosts
  from being returned by the dynamic inventory, at least after the cache is
  refreshed)
