Create DNS entries in IPA for openstack services

This adds forward and reverse DNS records for all services.

Without the reverse DNS entries, certificates cannot be created
for etcd which requires a subject alternative name (SAN) entry
to be included. This is used by cinder for A/A support.

The task is delegated to tripleo-ipa. It uses the host_entry
which is also used for managing the entries in /etc/hosts.
