Add healthcheck commands to docker-compose.yml (#9143)
This will allow Docker to be automatically check the health of services.

Docker won't do anything other than showing the state in the output of
"docker-compose ps" by default, but some management tools may watch for
container health events.

Here's what my local instance looks like right now:
