* 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.

* Autogenerate inventory/hosts when 'inventory: static' (Default),
with the shade-inventory tool.
* Drop unused anymore: openstack.py and associated GPL notes,
an example static inventory, omit manual updates for the
inventory DNS names in the deployment guide.
* Switch openstack.py formatted inventory hostvars
to the shade-inventory format (omit openstack.* from hostvars).
* Populate node labels from inventory vars instead of the heat
templates combined with inventory vars.
* Add app (k8s minions) nodes group for primary node labels.

Because openshift-ansible requires root on the cluster nodes, but it
doesn't explicitly set it in the playbooks (like we do), let's set it
in our inventory instead of requiring to pass `--become` to
`ansible-playbook`.
That will simplify the installation steps as well as let us include
the provisioning and openshift-ansible playbooks in a single playbook.

* Switch the sample inventory to CentOS
This changes the image name and deployment types to use centos instead
of rhel and sets `rhsm_register` to false.
With these changes, the inventory should be immediately deployable
using the default values (assuming the image, network and flavor names
match).
Ideally, the upstream CI will just end up using this inventory with
little to no changes, too at some point.
* Specify the origin openshift_release

* Add defaults values for some openstack vars
Ansible shows errors when the `rhsm_register` and
`openstack_flat_secgrp` values are not present in the inventory even
though they have sensible default values.
This makes them both default to false when they're not specified.
* Comment out the flat security group option in inv
It's no longer required to be there so let's comment it out.

Add a openstack_flat_secgroup, defaults to False.
When set, merges sec rules for master, node, etcd, infra nodes into a
single group. Less secure, but might help to mitigate quota limitations.
Update docs. Use timeout 30s to mitigate the error:
Timeout (12s) waiting for privilege escalation prompt.
