Code Review
This pull request introduces valuable event loop monitoring metrics to Ray Serve, which will be very helpful for debugging performance issues and blocked event loops. The implementation is well-structured, with a new event_loop_monitoring module cleanly integrated into the proxy, replica, and router components. The documentation is clear and comprehensive, and the tests cover the new functionality well. I have a couple of suggestions to improve the metric descriptions for better code clarity and to make the tests more robust.
