1. Use pod-level resource when feature is enabled and resources are set at pod-level 2. Edge case handling: When a pod defines only CPU or memory limits at pod-level (but not both), and container-level requests/limits are unset, the pod-level requests stay empty for the resource without a pod-limit. The container's request for that resource is then set to the default request value from schedutil.
