/**
 * Allows the relay to be shut down with an HTTP request, after which
 * docker-compose will restart it. This allows each test to have a clean
 * slate. The drawback is that the tests can't run in parallel, so the
 * test suite is very slow. A better option would be to have this relay
 * server manage the relay completely: star/stop isolated relay instances
 * with HTTP requests and allow multiple instances to run at the same
 * time so that the tests can be parallelized.
