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** Change-Id: I1880794717b9e47786ae255ea1afa57d805cde8e Signed-off-by: Kevin Carter <kevin.carter@rackspace.com>
