Subject: [PATCH] Add backwards-compat playbook for /etc/nodepool/provider

The TripleO CI legacy jobs rely on the /etc/nodepool/provider file
which is no longer provided in Zuul v3.
These variables are now available directly through Ansible but we're
mostly interested in getting the existing legacy jobs working for the
time being.
