Sahara Integration

Integration of OpenStack data processing service (sahara) with
TripleO.

- Deploys sahara in distributed mode (separate api and engine
  processes on each controller node)
- Load balancing w/haproxy
- RabbitMQ/MySQL supported per current TripleO standard
- Minimal configurability at this time
