[Metal] Enable firewall on OpenStack host
Issue
Kolla Ansible added support for firewall configuration in the Zed release. However, this project still has the firewall disabled.
Proposal
Enable firewall support.
Edit: Currently this feature doesn't seem to work as expected. Kolla Ansible doesn't open the API or web server ports in the firewall. Putting this on the back burner for now, will revisit for v2.2.x.
