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.
Provides an opt-in flag, --experimental-fail-swap-on (and corresponding
KubeletConfiguration value, ExperimentalFailSwapOn), which is false by default.

This is the first stab at getting the Kubelet running on Windows (fixes#30279), and getting it to deploy network-accessible pods that consist of Windows containers. Thanks @csrwng, @jbhurat for helping out.
The main challenge with Windows containers at this point is that container networking is not supported. In other words, each container in the pod will get it's own IP address. For this reason, we had to make a couple of changes to the kubelet when it comes to setting the pod's IP in the Pod Status. Instead of using the infra-container's IP, we use the IP address of the first container.
Other approaches we investigated involved "disabling" the infra container, either conditionally on `runtime.GOOS` or having a separate windows-docker container runtime that re-implemented some of the methods (would require some refactoring to avoid maintainability nightmare).
Other changes:
- The default docker endpoint was removed. This results in the docker client using the default for the specific underlying OS.
More detailed documentation on how to setup the Windows kubelet can be found at https://docs.google.com/document/d/1IjwqpwuRdwcuWXuPSxP-uIz0eoJNfAJ9MWwfY20uH3Q.

add script to check for updates to the files for generation
Adds a verify script to help people writing APIs remember to wire all the individual pieces up. Eventually it will be better to avoid this altogether, but this is a start.

Switch DisruptionBudget api from bool to int allowed disruptions [only v1beta1]
Continuation of #34546. Apparently it there is some bug that prevents us from having 2 different incompatibile version of API in integration tests. So in this PR v1alpha1 is removed until testing infrastructure is fixed.
Base PR comment:
Currently there is a single bool in disruption budget api that denotes whether 1 pod can be deleted or not. Every time a pod is deleted the apiserver filps the bool to false and the disruptionbudget controller sets it to true if more deletions are allowed. This works but it is far from optimal when the user wants to delete multiple pods (for example, by decreasing replicaset size from 10000 to 8000).
This PR adds a new api version v1beta1 and changes bool to int which contains a number of pods that can be deleted at once.

[Kubelet] Use the custom mounter script for Nfs and Glusterfs only
This patch reduces the scope for the containerized mounter to NFS and GlusterFS on GCE + GCI clusters
This patch also enabled the containerized mounter on GCI nodes
Shepherding multiple PRs through the submit queue is painful. Hence I combined them into this PR. Please review each commit individually.

rename kubelet flag mounter-path to experimental-mounter-path
```release-note
* Kubelet flag '--mounter-path' renamed to '--experimental-mounter-path'

The feature the flag controls is an experimental feature and this renaming ensures that users do not depend on this feature just yet.

Remove last probe time from replica sets
While experimenting with Deployment conditions I found out that if we are going to use lastProbeTime as we are supposed to be using it then we hotloop between updates (see https://github.com/kubernetes/kubernetes/pull/19343#issuecomment-255096778 for more info)

In order to be able to use new mounter library, this PR adds the
mounterPath flag to kubelet which passes the flag to the mount
interface. If flag is empty, mount uses default mount path.

**What this PR does / why we need it**:
Removes the deprecated configure-cbr0 flag and networking mode to avoid having untested and maybe unstable code in kubelet, see: #33789
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, #<issue_number>, ...)` format, will close that issue when PR gets merged)*:
fixes#30589fixes#31937
**Special notes for your reviewer**: There are a lot of deployments who rely on this networking mode. Not sure how we deal with that: force switch to kubenet or just delete the old deployment?
But please review the code changes first (the first commit)

Add PSP support for seccomp profiles
Seccomp support for PSP. There are still a couple of TODOs that need to be fixed but this is passing tests.
One thing of note, since seccomp is all being stored in annotations right now it breaks some of the assumptions we've stated for the provider in terms of mutating the passed in pod. I've put big warning comments around the pieces that do that to make sure it's clear and covered the rollback in admission if the policy fails to validate.
