Feature Request: docker-compose.yml

I've found it hard to get this code up and running due to the number of components/services that must be coordinated. Could a `docker-compose.yml` be added that starts a working stack comprised of TURN + STUN + provider + consumer to make running the code reproducible across platforms?

Start by mapping how the repository starts the TURN, STUN, provider, and consumer components and identify their configuration and entry points. Define a docker-compose.yml that coordinates those services into a working stack, then verify that the full application starts reproducibly across platforms.
