Remove manually written typed registries
These were only used in a handful of places, and were not consistently available for all types.
They add a lot of call sites for PRs like https://github.com/kubernetes/kubernetes/pull/65105 and are not generally useful (very few callers have the ability to construct the underlying store).
This PR switches the scale subresources to use the underlying store directly (like the status subresources already were), and removes the manually written Registry impls.

Derive kubelet serving certificate CSR template from node status addresses
xref https://github.com/kubernetes/features/issues/267fixes#55633
Builds on https://github.com/kubernetes/kubernetes/pull/65587
* Makes the cloud provider authoritative when recording node status addresses
* Makes the node status addresses authoritative for the kube-apiserver determining how to speak to a kubelet (stops paying attention to the hostname label when determining how to reach a kubelet, which was only done to support kubelets < 1.5)
* Updates kubelet certificate rotation to be driven from node status
* Avoids needing to compute node addresses a second time, and differently, in order to request serving certificates.
* Allows the kubelet to react to changes in its status addresses by updating its serving certificate
* Allows the kubelet to be driven by external cloud providers recording node addresses on the node status
test procedure:
```sh
# setup
export FEATURE_GATES=RotateKubeletServerCertificate=true
export KUBELET_FLAGS="--rotate-server-certificates=true --cloud-provider=external"
# cleanup from previous runs
sudo rm -fr /var/lib/kubelet/pki/
# startup
hack/local-up-cluster.sh
# wait for a node to register, verify it didn't set addresses
kubectl get nodes
kubectl get node/127.0.0.1 -o jsonpath={.status.addresses}
# verify the kubelet server isn't available, and that it didn't populate a serving certificate
curl --cacert _output/certs/server-ca.crt -v https://localhost:10250/pods
ls -la /var/lib/kubelet/pki
# set an address on the node
curl -X PATCH http://localhost:8080/api/v1/nodes/127.0.0.1/status \
-H "Content-Type: application/merge-patch+json" \
--data '{"status":{"addresses":[{"type":"Hostname","address":"localhost"}]}}'
# verify a csr was submitted with the right SAN, and approve it
kubectl describe csr
kubectl certificate approve csr-...
# verify the kubelet connection uses a cert that is properly signed and valid for the specified hostname, but NOT the IP
curl --cacert _output/certs/server-ca.crt -v https://localhost:10250/pods
curl --cacert _output/certs/server-ca.crt -v https://127.0.0.1:10250/pods

```
```release-note
* kubelets that specify `--cloud-provider` now only report addresses in Node status as determined by the cloud provider
* kubelet serving certificate rotation now reacts to changes in reported node addresses, and will request certificates for addresses set by an external cloud provider

Bugfix/csi default fs type
This PR address the issue mentioned in the following ticket https://github.com/kubernetes/kubernetes/issues/65122
The FSType string will now not be defaulted to ext4. Removes defaulting of CSI file system type to ext4. CSI plugins that depended on this default need to be updated as the fsType would remain an empty string if not provided and would not default to ext4. CSI spec allows for an empty fstype string. This is intended for non-block plugins like nfs and gluster where filesystems are not separately created on the volume. But currently the default file system is overridden to ext4 which makes the above case redundant. This commit prevents such an overridding.
```release-note
ACTION REQUIRED: Removes defaulting of CSI file system type to ext4. All the production drivers listed under https://kubernetes-csi.github.io/docs/Drivers.html were tested and work as expected after this change. If you are using a driver not in that list, please test the drivers on an updated test cluster first. ```

Allow more fields at root of CRD schema if status is enabled
Fixes https://github.com/kubernetes/kubernetes/issues/65293
Currently, we allow only `properties`, `required` and `description` at the root of the CRD schema when the status subresource is enabled.
We can also include some other fields, even though sometimes they might not make sense (but they don't harm).
The main idea is that when validation schema for status is extracted as `properties["status"]`, validation for status is not lost.
**Release note**:
```release-note
More fields are allowed at the root of the CRD validation schema when the status subresource is enabled.

Allow override of AllowCreateOnUpdate with new argument to Update
**What this PR does / why we need it**:
Changes the Update function signature to include a new bool which tells storage to override what the UpdateStrategy returns for AllowCreateOnUpdate. This is not exposed to the user, the handler is the one that sets this override value. Eventually the patch handler will set this to true, in order to provide more consistent apply behavior, without changing the existing PUT behavior.
