This is a complete DNS solution, with hidden master and bind9 slave.
It lacks the designate-sink service, because there is no true specification
to implement that. It listens for Nova/Neutron events and creates records
though adding those to just 1 domain isn't helping much in an environment
with multiple tenants.
