default nameservers. Technically, this allows to deploy OpenShift clusters
without dnsmasq proxies.

+If you want to use a two sets of hostnames for public and private/prefixed DNS
+records for your externally managed public DNS server, you can specify
+`openshift_openstack_public_hostname_suffix` and/or
+`openshift_openstack_private_hostname_suffix`. The suffixes will be added
+to the nsupdate records sent to the external DNS server. Those are empty by default.

+**Note** the real hostnames, Nova servers' or ansible hostnames and inventory
+variables will not be updated. The deployment may be done on arbitrary named
+hosts with the hostnames managed by cloud-init. Inventory hostnames will ignore
+the suffixes.
The `openstack_<role name>_hostname` is a set of variables used for customising
public names of Nova servers provisioned with a given role. When such a variable stays commented,
