kubectl: point info url to user guide overview
The kubectl command output suggests a user find more information at the
github source repo, eg:
$ kubectl --help
kubectl controls the Kubernetes cluster manager.
Find more information at https://github.com/kubernetes/kubernetes.
But there is curated user documentation available at, eg:
https://kubernetes.io/docs/reference/kubectl/overview/
which upon referencing yields a much better experience for a user than the
top of the source repo.

kubelet: include runtime error in event on CreatePodSandbox failure
Include the error from the runtime in the event message when CreatePodSandbox fails. The sandbox creation can fail for many reasons and including the error makes the situation easier to debug.
The event for failed PodSandboxStatus includes this information so there is already precedent for doing this.

Skip pods that refer to PVCs that are being deleted
**What this PR does / why we need it**:
New check was added to `Schedule()` to make sure that a scheduled pod refers to existing PVCs that are not being deleted.
In 1.9 we plan to add a new feature that uses finalizers on PVC to protect PVCs that are used by a running pod from being deleted. This finalizer will be removed when all pods that use a PVC are finished or deleted. See https://github.com/kubernetes/community/blob/master/contributors/design-proposals/storage/postpone-pvc-deletion-if-used-in-a-pod.md for details.
I needed to pass `pvcLister` to `GenericScheduler`.
UX:
```
$ kubectl describe pod
...

Make kubectl explain print the Kind and APIVersion of the resource
**What this PR does / why we need it**:
Kubectl explain currently doesn't print out the Kind and APIversion of the resource being explained. When running `kubectl explain hpa.spec`, for example, there is no way of knowing whether you're looking at the `autoscaling/v1` or the `autoscaling/v2beta1` version.
Also, `kubectl explain` is often used as a reference when writing YAML/JSON object manifests. It allows you to look up everything except the API version. Currently, you either need to know the API Version of a resource by heart or look it up in the online API docs.
This PR fixes both problems by having `kubectl explain` print out the full Kind and APIVersion of the resource it is explaining.
Here are a few examples of the new output:
```
$ kubectl explain deploy
KIND: Deployment
VERSION: extensions/v1beta1
DESCRIPTION:
...
$ kubectl explain hpa.spec
KIND: HorizontalPodAutoscaler
VERSION: autoscaling/v1
RESOURCE: spec <Object>
DESCRIPTION:

VERSION: autoscaling/v1
FIELD: maxReplicas <integer>
DESCRIPTION:

$ kubectl explain hpa.spec --recursive

RESOURCE: spec <Object>
DESCRIPTION:

Federation docs are already in project [federation](https://github.com/kubernetes/federation).

The printing level for node updated failed info should be used WARNING type
**What this PR does / why we need it**:
when I add the new node to the currnent kubernetes cluster, the kube-controller-manager always outputs the error msg( `Failed to set statusUpdateNeeded to needed true because nodeName="openpass-215" does not exist)` and (`Failed to update statusUpdateNeeded field in actual state of world: Failed to set statusUpdateNeeded to needed true because nodeName="openpass-215" does not exist`).
The results of invocation `updateNodeStatusUpdateNeeded` have two context, normal and abnormal.
The normal context is adding a new node to the cluster, the abnormal context is really exist some errors.
The printing level is confusing because it awlays outputs the error level msg.

Create{Container,Pod}SecurityContext: modify a pod and don't return the annotations
**What this PR does / why we need it**:
Prior https://github.com/kubernetes/kubernetes/pull/52849 we couldn't modify a pod and had to return annotations from the methods. But now, as we always working with a copy of a pod, we can modify it directly and we don't need to copy&return annotations separately.
This PR simplifies the code by modifying a pod directly. Also it renames these methods and replaces returning of the `SecurityContext` by in-place modification.
In fact it reverts the changes from https://github.com/kubernetes/kubernetes/pull/30257
**Release note**:
```release-note
NONE
