It turns out that the main blocker nats#190 was that `MQ_URL` was being overridden inside
`bluebird/run.py:16` and `bluebird/run.py:61`
This prevents the Flask server from coming up when running in a container.
Running `bluebird` locally should then be run in a way something like:
export MQ_URL="amqp://guest:guest@localhost:5672/%2F" && python run.py --sim-type=machcoll --sim-host=localhost
Whereas for running inside the docker container, this `$MQ_URL` should be `unset` _before_ firing
up, as the default (`MQ_URL=amqp://guest:guest@rabbitmq:5672/%2F`) is required for the connection to
take place.
