Add listener_port to provision_instance

API changes
- cannot change peers or enable
peers_from_control_nodes on VM deployments
- allow setting ip_address
- use ip_address over hostname in the generated
group_vars/all.yml
- Drop api/v2/peers endpoint

DB changes
- add ip_address unique constraint, but ignore "" entries

Other changes
- provision_instance should take listener_port option

Tests
- test that new controls doesn't disturb other peers
relationships
- test ip_address over hostname
