Set log level in RabbitMQ container to ERROR
At the moment the RMQ container is quite noisy. This is nice to have you can still do
docker logs [container] to filter out the noise for debugging but we're probably more interested in the logs from our containers than the logs from the rmq container.
Unfortunately it looks like it's not just an env var - you have to create a config file and pass it in which I guess probably means making our own rmq container Dockerfile.
