Where possible, we start the services on random ports, to avoid
port conflicts when parallelizing tests in the future.
When this isn't possible, we explicitly state the port, and wait for the
service to start. This is typically because the GraphQL Engine has already
started with knowledge of the relevant service passed in through an
environment variable.
