- Remove the deprecated metrics "scheduling_algorithm_preemption_evaluation_seconds" and "binding_duration_seconds", suggest to use "scheduler_framework_extension_point_duration_seconds" instead.

- Shell completion now knows to continue suggesting resource names when the command supports it.  For example `kubectl get pod pod1 <TAB>` will suggest more Pod names. ([#105711](https://github.com/kubernetes/kubernetes/pull/105711), [@marckhouzam](https://github.com/marckhouzam))
