Merge pull request #36330 from nikhiljindal/cascDelRS

Automatic merge from submit-queue Adding cascading deletion support to more federation controllers Ref #33612 Adding cascading deletion support for federated daemonsets and ingress. The code is same as that for namespaces. Just ensuring that DeletionHelper functions are called at right places in these controllers. e2e tests coming up in another PR. cc @kubernetes/sig-cluster-federation @caesarxuchao @madhusudancs @mwielgus ```release-note federation: Adding support for DeleteOptions.OrphanDependents for federated daemonsets and ingresses. Setting it to false while deleting a federated daemonset or ingress also deletes the corresponding resource from all registered clusters. ```
