This is a start at ansible-deployed nodepool environments.
We rename the minimal-nodepool element to nodepool-base-legacy, and
keep running that for the old nodes.
The groups are updated so that only the .openstack.org hosts will run
puppet. Essentially they should remain unchanged.
We start a nodepool-base element that will replace the current
puppet-<openstackci|nodepool> deployment parts. For step one, this
grabs project-config and links in the elements and config file.
A testing host is added for gate testing which should trigger these
roles. This will build into a full deployment test of the builder
container.
