* At the provisioning stage, allow users to auto-generate SSH config,
when using a static inventory.
* Run playbooks to provsion and post-provision as a separate, when
using a bastion. This re-applies the SSH config, which ansible can't
do on the fly.
* Support a pre-installed bastion node, colocated with the 1st infra
node.
* With a bastion enabled, reduce floating IP footprint to infra and
dns nodes only, effectively isolating a cluster in a private
network.

* At the provisioning stage, allow users to auto-generate a static
inventory w/o manual steps needed. The alternative to
go fully dynamic TBD.
* Move openshift pre-install playbook to the post provision playbook,
where the second part of the pre install tasks is already placed.

* 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.

The `wait_for_connection` module is more reliable as it uses Ansible's `ping`
to verify the nodes are really accessible. Using `wait_for` and checking that
port 22 is open runs into the possibility of SSH being up but the public keys
or users not being set up yet (as that's done with cloud-init).
In addition, we were gathering facts before running the wait_for task which
rendered it useless.

Prohibit sudoing for localhost played tasks, like DNS setup.
Re-use cached facts to speed up deployment.

Provision tasks use facts like ansible_hostname and few others.
W/o gathering facts, those expire, and the provision playbook cannot
be reapplied in order to update the existing heat stack.
Refresh the facts cache by specifying gather_facts: true.

They'll live in playbooks/provisioning/openstack from now on.
