Subject: [PATCH] Initial commit for adding ansible support

This adds a very basic structure to begin supporting ansible in Kolla.
Ansible can support complete idempotency, but wrapping docker-compose
does not allow idempotency at this time. These playbooks will be
extended to compensate for that in future patches.

+Koalla - Kolla with ansible!
+============================
+
+Koalla extends the Kolla project past [TripleO][] into its own bonified
+deployment system using [Ansible][] and [docker-compose][].
+
+[TripleO]: https://wiki.openstack.org/wiki/TripleO
+[Ansible]: https://docs.ansible.com
+[docker-compose]: http://docs.docker.com/compose
+
+
+Getting Started
+===============
+
+To run the ansible playbooks, you must specify an inventory file which tracks
+all of the available nodes in your environment. With this inventory file
+ansible will log into each node via ssh (configurable) and run tasks. Ansible
+does not require password less logins via ssh, however it is highly recommended
+to setup ssh-keys. More information on the ansible inventory file can be found
+[here][].
+
+[here]: https://docs.ansible.com/intro_inventory.html
+
+
+Deploying
+=========
+
+For AIO deploys, you can run the following commands. These will setup all of
+the containers on your localhost.
+
+```
+$ cd ./kolla/ansible
+$ ansible-playbook -i inventory/all-in-one site.yml
+```
+
+
+Further Reading
+===============
+
+Ansible playbook documentation can be found [here][].
