Public bug reported:
Description
===========
While configuring nova with neutron and designate to provide DNS to
instances, found that if use_neutron is not explicitly set to True in
nova.conf it gets ignored and dhcp_domain setting is used (novalocal by
default). I think designate does nothing here and the issue is between
nova and neutron configuration because if nova option is not used,
neutron default dns_domain would be openstacklocal.

This option allows you to specify the domain for the DHCP server.

"""),
Steps to reproduce
==================
No set use_neutron=True at nova.conf (is default)
Set dns_domain = sample.openstack.org. in neutron.conf
Boot an instance and check fqdn
Expected results
================
Instance have fqdn <vm-name>.sample.openstack.org
Actual results
==============
Instance have fqdn <vm-name>.novalocal
Environment
===========
CentOS
Source code from master
Deployed with kolla-ansible
neutron + ml2 + ovs
nova==16.0.0.0b2.dev511

If manually set use_neutron=True in nova.conf instance gets domain based
on dns_domain setting from neutron.
