Batch update feature gates for 1.22
Here is a second batch for feature gate updates in 1.22. - CPUManagerPolicyOptions kubernetes/kubernetes#101432 - ControllerManagerLeaderMigration kubernetes/kubernetes#103533 - DynamicKubeletConfig kubernetes/kubernetes#102966 - EndpointSliceProxying kubernetes/kubernetes#103451 - EndpointSliceTerminatingCondition kubernetes/kubernetes#103596 - HugePageStorageMediumSize kubernetes/kubernetes#99144 - JobTrackingWithFinalizers kubernetes/kubernetes#98817 (also tracked in kubernetes#28841, can rebase). - ServiceInternalTrafficPolicy kubernetes/kubernetes#103462 - WindowsEndpointSliceProxying kubernetes/kubernetes#103451 Some of these needs more detailed documentation.
