RabbitMQ container automatically quits

[cptfixit]

While starting the SKF stack with docker-compose I noticed that the RabbitMQ container will automatically quit with exitcode 0. i.e. this suggests that the job is done and Rabbit is no longer needed.

This coincides with errors from the SKF-API container.

skf-rabbitmq_container exited with code 0

Docker will show that the container indeed quit.
