Kevin Carter 2438ad03ab Added leap upgrade tooling
This change adds upgrade tooling that will take a Juno based
OpenStack-Ansible cloud and upgrade it to Newton. The tooling
will run a deployment through all of the needed steps upgrading
the environment and skipping all of the OpenStack releases in
between.

**This tooling should be considered experimental at this time**
