Why are these changes needed?
#2590 adds an e2e test for RayService HA with GCS FT. However, it is quite flaky. On my devbox, it has about a 50% chance of failing.
The reason is that when the GCS process on the head Pod is killed, the readiness/liveness probes on the worker Pod will fail for a while, causing some requests to be dropped. I no longer observe the issue after upgrading from Ray 2.9.0 to Ray 2.40.0.
