Merge pull request #6381 from bogdando/dns_hostname_prefixes
Automatic merge from submit-queue.
Allow 2 sets of hostnames for openstack provider
Support private/public hostnames suffixes for DNS records.
Real hostnames, Inventory variables, Nova servers and ansible
hostnames will ignore the custom suffixes. Those are only for
nsupdates sent to external DNS servers.
Related change: add openshift_openstack_public_dns_domain to
the role defaults to not rely on the group vars example only.
