When a Cloud Run container instance idles between requests and withdraws CPU, there is a lack of heartbeat from the worker to the gunicorn arbiter process. A service in this state can have "WORKER TIMEOUT" error logs once CPU is restored upon receiving an HTTP request.

The timeout on workers is not an essential part of server resource management. Per benoitc/gunicorn#2291, gunicorn supports setting an unlimited timeout with --timeout 0. Let's do that to clean up the logs.
