[services] Tunnelbroker - RabbitMQ Docker image for dev environment

Summary:
For a local Tunnelbroker development environment, we need to use a local instance of the RabbitMQ server.
Add the RabbitMQ docker image after the localstack image to the docker-compose.
AMQP(s) ports 5672 and 5671 are forwarded to use in local or docker builds.
The rabbitMQ management console is listening on localhost:15672.
The local image user and password are set to comm:comm.

Test Plan: Successfully connected to the rabbitMQ by AMQP client and logged into the local management web-gui.
