[openstack-dev] [tripleo][tripleo-quickstart] Multiple parallel deployments on a single virthost

I've just submitted a slew of changes to tripleo-quickstart with the
ultimate goal of being able to spin up multiple openstack deployments
in parallel on the same target virthost.

The meat of the change is an attempt to clearly separate the virthost
from the undercloud; we had several tasks that worked only because the
user name (and working directory) happened to be the same in both

With these changes in place, I am able to rapidly deploy multiple
tripleo-deployments on a single virthost, each one isolated to a
particular user account.  I'm using a playbook that includes
just the libvirt/setup, undercloud-deploy, and overlcoud-* roles.
This is extremely convenient for some of the work that I'm doing now.

This does require some pre-configuration on the virthost (each user
gets their own overcloud bridge) and in the quickstart (each user gets
their own underlcoud_external_network_cidr).
