Persist DNS configuration for nodes for openstack provider
* Firstly, provision a Heat stack with given public resolvers.
* After the DNS node configured as an authoritative server,
switch the Heat stack's Neutron subnet to that resolver
(private_dns_server) the way it to become the first entry pushed
into the hosts /etc/resolv.conf. It will be serving the cluster
domain requests for OpenShift nodes and workloads.
* Drop post-provision /etc/reslov.conf nameserver hacks as not
needed anymore.
* Fix dns floating IPs output and add the priv IPs output as well.
* Update docs, clarify localhost vs servers requirements, add
required Network Manager setup step.
* Use post-provision task names instead of comments.
