Never let cluster-scoped resources skip webhooks

Fix #57964

This allows user write webhooks for cluster-scoped custom resources.

We still need to figure out how to selectively exempt cluster-scoped resources from webhooks to avoid bootstrapping deadlocks. For now, if a deadlock occurs, users can work around by first deleting the webhook configuration, then rebooting the webhook, then re-enabling the webhook configuration.

```release-note
Bug fix: webhooks now do not skip cluster-scoped resources

Action required: Before upgrading your Kubernetes clusters, double check if you had configured webhooks for cluster-scoped objects (e.g., nodes, persistentVolume), these webhooks will start to take effect. Delete/modify the configs if that's not desirable.
```

apiserver

Generic library for building a Kubernetes aggregated API server.

Purpose

This library contains code to create Kubernetes aggregation server complete with delegated authentication and authorization, kubectl compatible discovery information, optional admission chain, and versioned types. It's first consumers are k8s.io/kubernetes, k8s.io/kube-aggregator, and github.com/kubernetes-incubator/service-catalog.

Compatibility

There are NO compatibility guarantees for this repository, yet. It is in direct support of Kubernetes, so branches will track Kubernetes and be compatible with that repo. As we more cleanly separate the layers, we will review the compatibility guarantee. We have a goal to make this easier to use in 2017.

Where does it come from?

apiserver is synced from https://github.com/kubernetes/kubernetes/blob/master/staging/src/k8s.io/apiserver. Code changes are made in that location, merged into k8s.io/kubernetes and later synced here.

Things you should NOT do

  1. Directly modify any files under pkg in this repo. Those are driven from k8s.io/kubernetes/staging/src/k8s.io/apiserver.
  2. Expect compatibility. This repo is changing quickly in direct support of Kubernetes and the API isn't yet stable enough for API guarantees.
