Add e2e node test for log path
fixes#34661
A node e2e test to check if container logs files are properly created with right content.
Since the log files under `/var/log/containers` are actually symbolic of docker containers log files, we can not use a pod to mount them in and do check (symbolic doesn't supported by docker volume).

**What this PR does / why we need it**:
This is the first stab at supporting kube-proxy (userspace mode) on Windows
**Which issue this PR fixes** :
fixes#30278
**Special notes for your reviewer**:
The MVP uses `netsh portproxy` to redirect traffic from `ServiceIP:ServicePort` to a `LocalIP:LocalPort`.
For the next version we are expecting to have guidance from Microsoft Container Networking team.
**Limitations**:
Current implementation does not support DNS queries over UDP as `netsh portproxy` currently only supports TCP. We are working with Microsoft to remediate this.

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.

Adding cadcading deletion support for federated secrets
Ref https://github.com/kubernetes/kubernetes/issues/33612
Adding cascading deletion support for federated secrets.
The code is same as that for namespaces. Just ensuring that DeletionHelper functions are called at right places in secret_controller.
Also added e2e tests.
cc @kubernetes/sig-cluster-federation @caesarxuchao
```release-note
federation: Adding support for DeleteOptions.OrphanDependents for federated secrets. Setting it to false while deleting a federated secret also deletes the corresponding secrets from all registered clusters.
```
The e2e tests cover cases like cluster size changed, parameters
changed, ConfigMap got deleted, autoscaler pod got deleted, etc.
They are separated into a fast part(could be run parallelly) and
a slow part(put in [serial]). The fast part of the e2e tests cost
around 50 seconds to run.

Rename ScheduledJobs to CronJobs
I went with @smarterclayton idea of registering named types in schema. This way we can support both the new (CronJobs) and old (ScheduledJobs) resource name. Fixes#32150.
fyi @erictune @caesarxuchao @janetkuo
Not ready yet, but getting close there...
**Release note**:
```release-note
Rename ScheduledJobs to CronJobs.
```
This allows us to interrupt/kill the executed command if it exceeds the
timeout (not implemented by this commit).
Set timeout in Exec probes. HTTPGet and TCPSocket probes respect the
timeout, while Exec probes used to ignore it.
Add e2e test for exec probe with timeout. However, the test is skipped
while the default exec handler doesn't support timeouts.

Adding more e2e tests for federated namespace cascading deletion and fixing bugs
Ref https://github.com/kubernetes/kubernetes/issues/33612
Adding more e2e tests for testing cascading deletion of federated namespace.
New tests are now verifying that cascading deletion happen when DeletionOptions.OrphanDependents=false and it does not happen when DeleteOptions.OrphanDependents=true.
Also updated deletion helper to always add OrphanFinalizer. generic registry will remove it if DeleteOptions.OrphanDependents=false. Also updated namespace registry to do the same.
We need to add the orphan finalizer to keep the orphan by default behavior. We assume that its dependents are going to be orphaned and hence add that finalizer. If user does not want the orphan behavior, he can do so using DeleteOptions and then the registry will remove that finalizer.

Add cmd support to gcp auth provider plugin
**What this PR does / why we need it**:
Adds ability for gcp auth provider plugin to get access token by shelling out to an external command. We need this because for GKE, kubectl should be using gcloud credentials. It currently uses google application default credentials, which causes confusion if user has configured both with different permissions (previously the two were almost always identical).
**Which issue this PR fixes**:
Addresses #35530 with gcp-only solution, as generic cmd plugin was deemed not useful for other providers.
**Special notes for your reviewer**:
Configuration options are to support whatever future command gcloud provides for printing access token of active user. Also works with existing command (`gcloud auth print-access-token`)

New command: "kubeadm token generate"
As part of #33930, this PR adds a new top-level command to kubeadm to just generate a token for use with the init/join commands. Otherwise, users are left to either figure out how to generate a token on their own, or let `kubeadm init` generate a token, capture and parse the output, and then use that token for `kubeadm join`.
At this point, I was hoping for feedback on the CLI experience, and then I can add tests. I spoke with @mikedanese and he didn't like the original propose of `kubeadm util generate-token`, so here are the runners up:
```
$ kubeadm generate-token # <--- current implementation
$ kubeadm generate token # in case kubeadm might generate other things in the future?
$ kubeadm init --generate-token # possibly as a subcommand of an existing one
```
Currently, the output is simply the token on one line without any padding/formatting:
```
$ kubeadm generate-token

```

Controller changes for perma failed deployments
This PR adds support for reporting failed deployments based on a timeout
parameter defined in the spec. If there is no progress for the amount
of time defined as progressDeadlineSeconds then the deployment will be
marked as failed by a Progressing condition with a ProgressDeadlineExceeded
reason.

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.

--v=2 is low noise (record changes), can be default
--v=3 will shows per request logging
Note: due to the code path with which we integrate with
skydns, we don't see non-PILLAR_DOMAIN requests, so these
will never be logged.
