CRI socket doesn't have to be an absolute path, it should be an url.
However, attempt to use it as an url in 'kubeadm init' command line
causes this validation error:
$ sudo ./kubeadm init --cri-socket unix:///var/run/crio/crio.sock
nodeRegistration.criSocket: Invalid value:
"unix:///var/run/crio/crio.sock": path is not absolute
Fixed by adding ValidateSocket function and using it in the
ValidateNodeRegistrationOptions check instead of ValidateAbsolutePath.
Make default component configs printable via `kubeadm config print-default`.
Component configs are not printed by default. You have to explicitly request
that for concrete API objects via the `--api-objects` command line parameter.
For a list of possible API objects use the help option.

Re-enable write-read pv check in volume provisioning tests
**What this PR does / why we need it**: Except for the recently-added CSI tests, every test that uses testDynamicProvisioning in volume_provisioning has been skipping the
`By("checking the created volume is writable and has the PV's mount options")`
and
`By("checking the created volume is readable and retains data")`
steps due to an unintentional change in https://github.com/kubernetes/kubernetes/pull/59879
**Special notes for your reviewer**: The 'attach' variable name is not descriptive at all, default behaviour is unclear. Tests will take longer of course, but that was always the intention, to not only test provisioning of PV is according to PVC but that you can actually r/w it (hence e2e).

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
ls -la /var/lib/kubelet/pki
# set an hostname and IP 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"},{"type":"InternalIP","address":"127.0.0.1"}]}}'
# 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 AND 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
ls -la /var/lib/kubelet/pki
```
```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

Remove DefaultingSerializer as it is not being used

Don't delete pkg/generated/bindata.go in make clean
**What this PR does / why we need it**: follow-up to #65985: `pkg/generated/bindata.go` has been re-added to the repo, so `make clean` shouldn't delete it, as doing so makes the tree dirty.
This is mostly problematic for jobs which run `make clean` followed by `make quick-release` or `make release` (like our CI build job), since those won't regenerate `pkg/generated/bindata.go`, as they run builds inside the build container.

Convert TestServerRunWithSNI to subtests to isolate flake
This test is flaking - make it easier to pin down where and why by
converting to subtests and making cleanup logic simpler. Also turn an
ignored listen error into a "fatal".
Make the test run in parallel to speed up individual runs and hopefully
flush out issues.
