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.

Fix kubectl drain for statefulset
Support deleting pets for `kubectl drain`.
Use evict to delete pods.
Fixes: #33727
```release-note
Adds support for StatefulSets in kubectl drain.
Switches to use the eviction sub-resource instead of deletion in kubectl drain, if server supports.
```
@foxish @caesarxuchao
We are moving towards marking master nodes as tainted, and not
necessarily unschedulable. Further now we encourage users to cordon
nodes, marking them unschedulable.
Thus the reliance on "Unschedulable" is not really a great indicator for
the master.
So, 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

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.

have basic kubectl crud agnostic of registered types
Makes `kubectl get` agnostic to scheme (baked in API types). This means that it will now work against generic API servers that are "kube shaped".
This is similar to the work done for `kubectl create` last release. I'll split out the smaller command. `kubectl get` looks a lot different, but this eliminates all special casing for TPR in those cases.

kubectl: make edit work with lists again
@kubernetes/kubectl this is fixing https://github.com/kubernetes/kubernetes/issues/20519 and slightly changes the behavior of --recursive when the directory that is being edited has files with errors. Previously since `edit` was working on an object basis, bad objects would be skipped and the editor would load the next object. We want to load multiple objects in the same list and it's impossible to load invalid objects in a list so --recursive will not work if there is any error in the directory. I think this is an acceptable trade-off.

Curating Owners: pkg/kubectl
In an effort to expand the existing pool of reviewers and establish a
two-tiered review process (first someone lgtms and then someone
experienced in the project approves), we are adding new reviewers to
existing owners files.
## If You Care About the Process:
We did this by algorithmically figuring out who’s contributed code to
the project and in what directories. Unfortunately, that doesn’t work
well: people that have made mechanical code changes (e.g change the
copyright header across all directories) end up as reviewers in lots of
places.
Instead of using pure commit data, we generated an excessively large
list of reviewers and pruned based on all time commit data, recent
commit data and review data (number of PRs commented on).
At this point we have a decent list of reviewers, but it needs one last
pass for fine tuning.
## TLDR:
As an owner of a sig/directory and a leader of the project, here’s what
we need from you:
1. Comment on the pull-request explaining the changes you want. I'll
take care of doing them (unless you want to modify the pull-request
yourself).
2. OWNERS files in subdirectory can be removed if they are redundant with
top-directory files.
3. Please use the ALIAS feature if you want to re-use a list of persons
in different files.
Pods which are evicted by the nodecontroller due to network
malfunction, or unresponsive kubelet should be differentiated
from termination initiated by other sources. The reason/message
are consumed by kubectl to provide a better summary using get/describe.

always allow decoding of status when returned from the API
`unversioned.Status` should be able to come back from any API version and still be properly decoded. This doesn't happen today by default.
@smarterclayton Our projectrequest endpoint returns a `Status` object on a 200 return from list to indicate everything went well. This (or something like it) is needed to make the API accepted by `kubectl`. Alternatively, we change the API to return a different (still not a `Project`) value from list, which still feels wrong.
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 previous attempt at the PR (PR#35050) was reverted for causeing a flake.
I believe that setting the deployments terminationGracePeriodSeconds to 0 should
take care of it. I ran hack/make-rules/test-cmd.sh 50 times in a row without encountering

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)

clean up client version negotiation to handle no legacy API
Version negotiation fails if the legacy API endpoint isn't available.
This tightens up the negotiation interface based to more clearly express what each stage is doing and what the constraints on negotiation are. This is needed to speak to generic API servers.
@kubernetes/kubectl
--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.
Calling `internalclientset.New()` with a rest client as an argument simply
copies that rest client to all the API group clients irrespective of the
configured GroupVersion or versionedAPIPath in the client. So only one
API group client gets the client configured correctly for that API
group. All the other API group clients get misconfigured rest clients.
On the other hand, `internalclientset.NewForConfigOrDie()` does the right
thing by reconfiguring the passed configs for each API group and
initializes an appropriate rest client for that group.
Now that we are relying on the `NewForConfigOrDie()` method to
initialize the rest clients, we need to swap the underlying http clients
in each of these rest clients with a fake one for testing.

Improvements to CLI usability and maintainability
Improves `kubectl` from an usability perspective by
1. Fixing how we handle terminal width in help. Some sections like the flags use the entire available width, while others like long descriptions breaks lines but don't follow a well established max width (screenshot below). This PR adds a new responsive writer that will adjust to terminal width and set 80, 100, or 120 columns as the max width, but not more than that given POSIX best practices and recommendations for better readability.
2. Adds our own normalizers for long descriptions and cmd examples which allows us better control about how things like lists, paragraphs, line breaks, etc are printed. Features markdown support. Looks like `templates.LongDesc` and `templates.Examples` instead of `dedent.Dedend`.
3. Allows simple reordering and reuse of help and usage sections.
3. Adds `verify-cli-conventions.sh` which intends to run tests to make sure cmd developers are using what we propose as [kubectl conventions](https://github.com/kubernetes/kubernetes/blob/master/docs/devel/kubectl-conventions.md). Just a couple simple tests for now but the framework is there and it's easy to extend.
4. Update [kubectl conventions](https://github.com/kubernetes/kubernetes/blob/master/docs/devel/kubectl-conventions.md) to use our own normalizers instead of `dedent.Dedent`.

The zsh completion output makes a call to "compinit" which causes the

This in-turn caused other commands' completions to break (such as git,
gcloud, vim) causing an error "function definition file not found" to
be returned any time a tab-completion was attempted.
This patch removes the call to `compinit` in the zsh completion output,

**Which issue this PR fixes**: fixes#33457
**Special notes for your reviewer**:
1. Is it possible to expose multiple external ips on the node?
2. Should this be supported or first one be taken like now?
3. Should more node address types be shown?
I'll add tests if solution is approved.

remove testapi.Default.GroupVersion
I'm going to try to take this as a series of mechanicals. This removes `testapi.Default.GroupVersion()` and replaces it with `registered.GroupOrDie(api.GroupName).GroupVersion`.
@caesarxuchao I'm trying to see how much of `pkg/api/testapi` I can remove.

Add kubelet awareness to taint tolerant match caculator.
Add kubelet awareness to taint tolerant match caculator.
Ref: #25320
This is required by `TaintEffectNoScheduleNoAdmit` & `TaintEffectNoScheduleNoAdmitNoExecute `, so that node will know if it should expect the taint&tolerant
Some of the main changes:
- add dryrun to annotate (can push this in a different PR if requested)
- use Complete(), Validate() and RunX()
- don't place dynamic variables in the options (only user options and args)
- call the NewBuilder() in the Run function.
You can now do diff between these files and they are as identical as possible.

Add option to set a service nodeport
**Release note**:
```release-note
Add kubectl --node-port option for specifying the service nodeport
```
This patch adds the option to set a nodeport when creating a NodePort
service. In case of a port allocation error due to a specified port
being out of the valid range, the error now includes the valid
range. If a `--node-port` value is not specified, it defaults to zero, in
which case the allocator will default to its current behavior of
assigning an available port.
This patch also adds a new helper function in `cmd/util/helpers.go` to
retrieve `Int32` cobra flags.
**Example**
```
# create a nodeport service with an invalid port
$ kubectl create service nodeport mynodeport --tcp=8080:7777 --node-port=1
The Service "mynodeport" is invalid: spec.ports[0].nodePort: Invalid
value: 1: provided port is not in the valid range. Valid ports range
from 30000-32767
# create a nodeport service with a valid port
$ kubectl create service nodeport mynodeport --tcp=8080:7777 --node-port=30000
service "mynodeport" created
# create a nodeport service with a port already in use
$ kubectl create service nodeport mynodeport --tcp=8080:7777 --node-port=30000
The Service "mynodeport" is invalid: spec.ports[0].nodePort: Invalid value: 3000: provided port is already allocated

Allow empty annotation values
Related downstream issue: https://github.com/openshift/origin/issues/11175
**Release note**:
```release-note
release-note-none
```
Annotations with empty values can be used, for example, in diagnostics
logging. This patch removes the client-side check for empty values in
an annotation key-value pair.
**Before**
```
$ kubectl annotate pod zookeeper-1 node-selector="" --overwrite
error: invalid annotation format: node-selector=
```
**After**
```
$ kubectl annotate pod zookeeper-1 node-selector="" --overwrite
pod "zookeper-1" annotated
```
```
$ kubectl get po/zookeeper-1 --template='{{.metadata.annotations}}'
map[... node-selector: test-label:test]

add linebreak between resource groups
**Release note**:
```release-note
release-note-none
```
Printing multiple groups via `kubectl get all` can produce output that is
hard to read in cases where there are a lot of resource types to display
/ some resource types contain varying column amounts.
This patch adds a linebreak above each group of resources only when
there is more than one group to display, and always omitting the
linebreak above the first group. This makes for slightly improved
output.
Linebreaks are printed to stderr, and honor the `--no-headers` option.
