Use already Deployed/Installed servers

This patch provides a set of templates that enables
tripleo-heat-templates to be used with a set of already deployed,
installed, and running servers. In this method, Nova and Ironic are not
used to deploy any servers.

This approach is attractive for POC deployments where dedicated
provisioning networks are not available, or other server install methods
are dictated for various reasons.

There are also assumptions that currently have to be made about the software
installed on the already deployed servers.  Effectively, they must match the
standard TripleO overcloud-full image.
