Review Comment:
When a Kubernetes liveness probe fails, the kubelet triggers a container
restart by first sending a SIGTERM signal to the main process. By default,
Kubernetes waits for the pod-level terminationGracePeriodSeconds for the
process to exit gracefully; and it will send SIGKILL only after the grace
period ends.
If one sets a long termination grace period to avoid interrupting long
running tasks on worker rollouts, they might still want the worker to be
quickly restarted if it becomes unhealthy instead of waiting for the whole pod
level grace period to run out.
