[abhas]

I have added a Dockerfile to make it easy for someone to run Colossus via Docker. The container also packages rabbitmq-server for easy integration with Celery. A pre-compiled image exists as well.

Hi, I am doing the install and was wondering if you could walk me through a basic configuration of Colossus to connect to RabbitMQ? The ReadMe just says "configure Colossus to use RabbitMQ" and I'm not sure what to do.
