x509 authenticator: get groups from subject's organization field
Note that the current X509 tests provide a bunch of certs but no private keys or commands to reproduce the testdata, so the new test case isn't added to the certificate chain.

Add benchmark to jenkins
This PR contains the following changes:
1. Add more tests in density benchmark test;
2. Add the peak value (100%) in latency and CPU usage statistic data;
3. Move the Ginkgo focus flag from e2e_remote.go to run_e2e.go;
4. Support running benchmark in run_e2e.go. The benchmark configuration file is an extension of image configuration. Each item requires additional GCE machine type (e.g. n1-standard-1, default value will be used if empty) and test names (Ginkgo focus regex strings). A test item is regarded as benchmark if the tests field is non-empty.

Move init-container feature from alpha to beta.
```release-note
Moved init-container feature from alpha to beta.
In 1.3, an init container is specified with this annotation key
on the pod or pod template: `pods.alpha.kubernetes.io/init-containers`.
In 1.4, either that key or this key: pods.beta.kubernetes.io/init-containers`,
can be used.
When you GET an object, you will see both annotation keys with the same values.
You can safely roll back from 1.4 to 1.3, and things with init-containers
will still work (pods, deployments, etc).
If you are running 1.3, only use the alpha annotation, or it may be lost when
rolling forward.
The status has moved from annotation key
`pods.beta.kubernetes.io/init-container-statuses` to
`pods.beta.kubernetes.io/init-container-statuses`.
Any code that inspects this annotation should be changed to use the new key.
State of Initialization will continue to be reported in both pods.alpha.kubernetes.io/initialized
and in `podStatus.conditions.{status: "True", type: Initialized}`
```
Mini-design for this change:
Goals:
1. A user can create an object with the beta annotation
on 1.4, and it works. The fact that the annotation has beta
in it communicates to the user that the feature is beta,
and so the user should have confidence in using it. Preferably,
when the user gets the annotation back, he see the beta
annotation.
1) If someone had an existing alpha object in their apiserver,
such as a RS with a pod template with an init-containers
annotation on it, it should continue to work (init containers
run) when stack upgraded to 1.4.
2) If someone is using a chart or blog post that has alpha
annotation on it and they create it on a 1.4 cluster, it should
work.
3) If someone had something with an init container in 1.4
and they roll back stack to 1.3, it should not silently stop
working (init containers don't run anymore).
To meet all these, we mirror an absent beta label from the alpha
key and vice versa. If they are out of sync, we use the alpha
one. We do this in conversion since there was already logic there.
In 1.3 code, all annotations are preserved across a round trip
(v1 -> api -> v1), and the alpha annotation turns into the internal
field that kubelet uses.
In 1.4 code, the alpha annotation is always preserved across
a round trip, and a beta annotation is always set equal to
the alpha one, after a round trip.
Currently, the kubelet always sees the object after a round trip
when it GETs it. But, we don't want to rely on that behavior,
since it will break when fastpath is implemented.
So, we rely on this:
all objects either are created with an alpha annotation (1.3 or 1.4
code) or are created with a beta annotation under 1.4. In the later
case, they are round tripped at creation time, and so get both
annotations. So all subsequent GETs see both labels.

rkt: Support subPath volume mounts feature
So that at most one volume object will be created for every unique
host path. Also the volume's name is random generated UUID to avoid
collision since the mount point's name passed by kubelet is not
guaranteed to be unique when 'subpath' is specified.
Should partially fix https://github.com/kubernetes/kubernetes/issues/26986
The non-existing host path creation issue is not touched here.

Add support for the standard objectmeta field selectors
certificates API was missing standard field selectors (noticed in 4120179db5 (r75413160))
also silences client-side warnings when using field selectors that don't have a registered client-side transformation (no functional change, since we were already returning the original field/value). if we want to trend toward embedding less conversion logic in our clients, I don't see us fully duplicating field selector conversions client-side to make that warning disappear.

Add spec.nodeName and spec.serviceAccountName to downward env var
The serviceAccountName is occasionally useful for clients running on
Kube that need to know who they are when talking to other components.
The nodeName is useful for PetSet or DaemonSet pods that need to make
calls back to the API to fetch info about their node.
Both fields are immutable, and cannot easily be retrieved in another
way.

```release-note
The `valueFrom.fieldRef.name` field on environment variables in pods and objects with pod templates now allows two additional fields to be used:
* `spec.nodeName` will return the name of the node this pod is running on
* `spec.serviceAccountName` will return the name of the service account this pod is running under

**What this PR does / why we need it**: This is an implementation of the [image provenance proposal](https://github.com/kubernetes/kubernetes/blob/master/docs/proposals/image-provenance.md). It also includes the API definitions by @Q-Lee from https://github.com/kubernetes/kubernetes/pull/30241
**Special notes for your reviewer**:
Please note that this is the first admission controller to make use of the admission controller config file (`--admission-controller-config-file`). I have defined a format for it but we may want to double check it's adequate for future use cases as well.
The format defined is:
```
{
"imagePolicy": {
"kubeConfigFile": "path/to/kubeconfig/for/backend",
"allowTTL": 50, # time in s to cache approval
"denyTTL": 50, # time in s to cache denial
"retryBackoff": 500, # time in ms to wait between retries
"defaultAllow": true # determines behavior if the webhook backend fails
}
}
```
