The ironic_dnsmasq container is currently tied to the ironic-conductor
Ansible group. It is required only for Ironic inspector and should
really either be tied to the ironic-inspector group or have a new
ironic-dnsmasq group defined for it. This problem means that if all
hosts are removed from the ironic-inspector group I will still have an
ironic_dnsmasq container deployed.

This change uses the ironic-inspector group to determine where to place
the ironic_dnsmasq container.

Currently the ironic_dnsmasq container does not support

interface with a different hostname. So it is OK to run nova-compute and
nova-compute-ironic on the same node.
