CSI Cluster Registry and Node Info CRDs
**What this PR does / why we need it**:
Introduces the new `CSIDriver` and `CSINodeInfo` API Object as proposed in https://github.com/kubernetes/community/pull/2514 and https://github.com/kubernetes/community/pull/2034
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes https://github.com/kubernetes/features/issues/594
**Special notes for your reviewer**:
Per the discussion in https://groups.google.com/d/msg/kubernetes-sig-storage-wg-csi/x5CchIP9qiI/D_TyOrn2CwAJ the API is being added to the staging directory of the `kubernetes/kubernetes` repo because the consumers will be attach/detach controller and possibly kubelet, but it will be installed as a CRD (because we want to move in the direction where the API server is Kubernetes agnostic, and all Kubernetes specific types are installed).
**Release note**:
```release-note
Introduce CSI Cluster Registration mechanism to ease CSI plugin discovery and allow CSI drivers to customize Kubernetes' interaction with them.
```

kube-ctrl-mgr: enable secure port 10257
This PR enables authn+authz (delegated to the kube-apiserver) and the secure port 10257 for the kube-controller-manager. In addition, the insecure port is disabled.
Moreover, it adds integration test coverage for the `--port` and `--secure-port` flags, plus the testserver infrastructure to tests flags in general inside integration tests.
```release-note
Enable secure serving on port 10257 to kube-controller-manager (configurable via `--secure-port`). Delegated authentication and authorization have to be configured like for aggregated API servers.

kubeadm: Drop arch suffixes
**What this PR does / why we need it**:
This change removes arch suffixes from control plane images (etcd, kube-apiserver, kube-scheduler, kube-proxy, etc.). These are not needed, as almost all control plane images have a fat manifest now. It also adds a missing unit test for `GetGenericImage`
We have arch suffixes only for kube-dns images now.

```

Move kubeproxy ComponentConfig external types to `k8s.io/kube-proxy`
**What this PR does / why we need it**:
This PR implements most of kubernetes/community#2354 for the kube-proxy.
The PR:
- Moves k8s.io/kubernetes/pkg/proxy/apis/kubeproxyconfig as-is to k8s.io/kubernetes/pkg/proxy/apis/config as agreed
- Moves the external types to the new staging repo k8s.io/kube-proxy, in the k8s.io/kube-proxy/config/v1beta1 package.
- Makes k8s.io/kubernetes/pkg/proxy/apis/config/v1beta1 source the types from k8s.io/kube-proxy/config/v1beta1. The defaulting and conversion code is kept in this package as before.
- All references to these packages have been updated.
Ref #67233
**Special notes for your reviewer**:
**Release note**:
```release-note
kube-proxy v1beta1 external ComponentConfig types are now available in the `k8s.io/kube-proxy` repo
