This isn't DNS related. Here, cloud-init must right the VM hostname in
/etc/hosts (using 127.0.1.1) so that it is able to resolve itself, even
when there's no outbound connectivity (and therefore, no DNS access).
The OpenStack image has been behaving like this since the beginning, I
see no valid reason why we would change the default behavior.
