ToJSON in pkg/kubectl/resource/visitor.go#ValidateSchema is unnecessary, because "data" will be checked in schema.ValidateBytes [pkg/api/validation/schema.go] shortly.

Extend all to more resources

Added more things from the list here:
https://github.com/kubernetes/kubernetes/blob/master/pkg/kubectl/cmd/cmd.go#L159

Note, did not add events as it did not seem useful to me. Since
this is just a list of messages generated by the system.

add union registry for quota

Document space shuttle style in controller/volume

Reverts #28813 and #28111.

@xiang90, I really appreciate the effort that went into your PRs (and think, in general, code simplification is a worthwhile effort), but the style in this controller was intentional to ensure that every branch is covered.  The verbosity and branchyness of this controller stores a lot of context and knowledge about how this subsystem is meant to function, so we need to put them back in.

Use the CNI bridge plugin to set hairpin mode

Following up this part of #23711:

>  I'd like to wait until containernetworking/cni#175 lands and then just pass the request through to CNI.

The code here just
 * passes the required setting down from kubenet to CNI
 * disables `DockerManager` from doing hairpin-veth, if kubenet is in use

Note to test you need a very recent version of the CNI `bridge` plugin; the one brought in by #28799 should be OK.

Add support to quota pvc storage requests

Adds support to quota cumulative `PersistentVolumeClaim` storage requests in a namespace.

Per our chat today @markturansky @abhgupta - this is not done (lacks unit testing), but is functional.

This lets quota enforcement for `PersistentVolumeClaim` to occur at creation time.  Supporting bind time enforcement would require substantial more work.  It's possible this is sufficient for many, so I am opening it up for feedback.

In the future, I suspect we may want to treat local disk in a special manner, but that would have to be a different resource altogether (i.e. `requests.disk`) or something.

Example quota:

```
apiVersion: v1
kind: ResourceQuota
metadata:
  name: quota
spec:
  hard:
    persistentvolumeclaims: "10"
    requests.storage: "40Gi"
```

e2e-runner: Remove quotes from jq output

Recent GCI e2e test failures suggest that the image name was double quoted when
passed to gcloud. E.g.,

```
09:59:51  - Invalid value for field
'resource.disks[0].initializeParams.sourceImage':
'https://www.googleapis.com/compute/v1/projects/container-vm-image-staging/global/images/"gci-base-53-8530-36-0"'.
The referenced image resource cannot be found.
```

The `-r`, or `--raw-output` option strips quotes from jq's output. With this
change, the output looks like:

```
+ export KUBE_GCE_MASTER_IMAGE=gci-base-54-8650-0-0  # Not quoted
```

@spxtr Can you review this XS PR? All of our e2e jobs are failing due to this.

Also, this was a bug introduced by #29631. I tried several times to duplicate the Kubekins instance locally, but still couldn't get it running. It would be GREAT if Jenkins changes can be tested before getting merged. :)

E2E & Node E2E: Add exec util in framework

For #29081.
Based on #29092 and #29494.

For first commit is a squashed commit of all old commits.
**The last 2 commits are new.**

This PR added exec util in framework, and moved `privileged.go` and `kubelet_etc_hosts` into `common` directory.

This will make the manual changes in https://github.com/kubernetes/kubernetes.github.io/pull/369 persist.

I still need to bump up the gcr.io/google_containers/gen-swagger-docs image version. I'll do that after I get LGTM here.

Node E2E: Make node e2e parallel

For https://github.com/kubernetes/kubernetes/issues/29081.
Fix https://github.com/kubernetes/kubernetes/issues/26215.
Based on https://github.com/kubernetes/kubernetes/pull/28807, https://github.com/kubernetes/kubernetes/pull/29020, will rebase after they are merged.

**Only the last commit is new.**

We are going to move more tests into the node e2e test. However, currently node e2e test only run sequentially, the test duration will increase quickly when we add more test.

This PR makes the node e2e test run in parallel so as to shorten test duration, so that we can add more test to improve the test coverage.

* If you run the test locally with `make test-e2e-node`, it will use `-p` ginkgo flag, which uses `(cores-1)` parallel test nodes by default.
* If you run the test remotely or in the Jenkin, the parallelism will be controlled by the environment variable `PARALLELISM`. The default value is `8`, which is reasonable for our test node (n1-standard-1).

Before this PR, it took  **833.592s** to run all test on my desktop.
With this PR, it only takes **234.058s** to run.

The pull request node e2e run with this PR takes **232.327s**.
The pull request node e2e run for other PRs takes **673.810s**.

Adding GCI to node e2e.

Depends on https://github.com/kubernetes/kubernetes/pull/29486
Adding the dev release as of now since stable and beta run docker v1.9.1
which is incompatible with kubelet.

Trigger container cleanup within a pod when a container exiting event is detected

#25239

If the resource in the delete call does not exist, the runtime should
not return an error. This eliminates the need for kubelet to define a
resource "not found" error that every runtime has to return.
