Fix kubectl Stratigic Merge Patch compatibility
As @smarterclayton pointed out in [comment1](https://github.com/kubernetes/kubernetes/pull/35647#pullrequestreview-8290820) and [comment2](https://github.com/kubernetes/kubernetes/pull/35647#pullrequestreview-8290847) in PR #35647,
we cannot assume the API servers publish version and they shares the same version.
This PR removes all the calls of GetServerSupportedSMPatchVersion().
Change the behavior of `apply` and `edit` to:
Retrying with the old patch version, if the new version fails.
Default other usage of SMPatch to the new version, since they don't update list of primitives.
fixes#36916

remove TPR registration, ease validation requirements
Fixes https://github.com/kubernetes/kubernetes/issues/36007 .
This removes the special casing for TPRs inside of the `UnstructuredObject`, which should allow CRUD against skewed kube api server levels.

make kubectl create --edit iterate
`kubectl create --edit` is broken after #36148 merged.
`kubectl create --edit` will fail when a manifest that contains multiple resources.
I guess the root cause is that dynamic typer doesn't support a list of resources currently.
This PR makes `kubectl create --edit` iterate again as `kubectl create`.

V2resource fixes
when using kubectl set resources it resets all resource fields that are not being set.
for example
$ kubectl set resources deployments nginx --limits=cpu=100m
followed by
$ kubectl set resources deployments nginx --limits=memory=256Mi
would result in the nginx deployment only limiting memory at 256Mi with the previous
limit placed on the cpu being wiped out. This behavior is corrected so that each invocation
only modifies fields set in that command and changed the testing so that the desired behavior
is checked.
Also a typo:
you must specify an update to requests or limits or (in the form of --requests/--limits)
corrected to
you must specify an update to requests or limits (in the form of --requests/--limits)
Implemented both the dry run and local flags.
Added test cases to show that both flags are operating as intended.
Removed the print statement "running in local mode" as in PR#35112
The original PR associated with these fixes where reverted due to causing a flake in hack/make-rules/test-cmd.sh, I gave the 'kubectl set resources' tests there own deployment and set the terminationGracePeriodSeconds to 0 and have run test-cmd.sh for hours without hitting the flake

kubectl: add less verbose version
The kubectl version output is very complex and makes it hard for users
and vendors to give actionable information. For example during the
recent Kubernetes 1.4.3 TLS security scramble I had to write a one-liner
for users to get out the version number to give to figure out if they
are vulnerable:
```
$ kubectl version | grep -i Server | sed -n 's%.*GitVersion:"\([^"]*\).*%\1%p'
```
Instead this patch outputs simply output by default
```
./kubectl version
Client Version: v1.4.3
Server Version: v1.4.3
```
Adding the `--verbose` flag will output the old format.

Fix handling lists in kubectl convert
Fixes https://github.com/kubernetes/kubernetes/issues/36722
When handling multiple objects in `kubectl convert` (for example in `kubectl convert -f .` with multiple files in current directory) the objects must be managed as a list instead of individually, otherwise `-o yaml|json` will generate invalid format (just multiple json/yaml objects concatenated) which can't be fed to `kubectl create` like in `kubectl convert -f . | kubectl create -f -`.
```release-note

Fix strategic patch for list of primitive type with merge sementic
Fix strategic patch for list of primitive type when the patch strategy is `merge`.
Before: we cannot replace or delete an item in a list of primitive, e.g. string, when the patch strategy is `merge`. It will always append new items to the list.
This patch will generate a map to update the list of primitive type.
The server with this patch will accept either a new patch or an old patch.
The client will found out the APIserver version before generate the patch.
Fixes#35163, #32398

kubectl: show node label if defined
We are moving towards marking master nodes as tainted, and not
necessarily unschedulable. Further now we encourage users to taint
nodes, marking them unschedulable.
Thus the reliance on "Unschedulable" is not really a great indicator for
the master.
Instead, recognize the existing node 'role' markers, and surface them
where Unschedulable is (in the status).
We recognize:
* a kubernetes.io/role label
* a kubeadm.alpha.kubernetes.io/role label
~a taint with Key 'dedicated'~

Support persistent volume usage for kubernetes running on Photon Controller platform
**What this PR does / why we need it:**
Enable the persistent volume usage for kubernetes running on Photon platform.
Photon Controller: https://vmware.github.io/photon-controller/
_Only the first commit include the real code change.
The following commits are for third-party vendor dependency and auto-generated code/docs updating._
Two components are added:
pkg/cloudprovider/providers/photon: support Photon Controller as cloud provider
pkg/volume/photon_pd: support Photon persistent disk as volume source for persistent volume
Usage introduction:
a. Photon Controller is supported as cloud provider.
When choosing to use photon controller as a cloud provider, "--cloud-provider=photon --cloud-config=[path_to_config_file]" is required for kubelet/kube-controller-manager/kube-apiserver. The config file of Photon Controller should follow the following usage:
```
[Global]
target = http://[photon_controller_endpoint_IP]
ignoreCertificate = true
tenant = [tenant_name]
project = [project_name]
overrideIP = true
```
b. Photon persistent disk is supported as volume source/persistent volume source.
yaml usage:
```
volumes:
- name: photon-storage-1
photonPersistentDisk:
pdID: "643ed4e2-3fcc-482b-96d0-12ff6cab2a69"
```
pdID is the persistent disk ID from Photon Controller.
c. Enable Photon Controller as volume provisioner.
yaml usage:
```
kind: StorageClass
apiVersion: storage.k8s.io/v1beta1
metadata:
name: gold_sc
provisioner: kubernetes.io/photon-pd
parameters:
flavor: persistent-disk-gold
```
The flavor "persistent-disk-gold" needs to be created by Photon platform admin before hand.

Add --force to kubectl delete and explain force deletion
--force is required for --grace-period=0. --now is == --grace-period=1.
Improve command help to explain what graceful deletion is and warn about
force deletion.
Part of #34160 & #29033
```release-note
In order to bypass graceful deletion of pods (to immediately remove the pod from the API) the user must now provide the `--force` flag in addition to `--grace-period=0`. This prevents users from accidentally force deleting pods without being aware of the consequences of force deletion. Force deleting pods for resources like StatefulSets can result in multiple pods with the same name having running processes in the cluster, which may lead to data corruption or data inconsistency when using shared storage or common API endpoints.
