Prevent dns resolution recursion (loop).
The dnsmasq should not be resolving the example.com recursively, because
in case that we have /etc/NetworkManager/dnsmasq.d/libvirt_dnsmasq.conf:
server=/example.com/192.168.55.1
the dnsmasq will be asking itself, therefore a dns resolution loop is
created, which causes
Maximum number of concurrent DNS queries reached (max: 150)
and performance degradation of dns resolution on the whole hypervizor and
guests.
This patch will fix that in the domain.xml, which will cause adding
local=/example.com/
to the /var/lib/libvirt/dnsmasq/openshift-ansible.conf, effectively
fixing the problem.
