update list of vailable resources
Hi,
kubectl get --help produce a list of resource types and aliases :
```
Valid resource types include:
* clusters (valid only for federation apiservers)
* componentstatuses (aka 'cs')
...
```
``` release-note
Update the list of resources in kubectl get --help
```
The list is currently outdated (for exemple missing networkpolicy).
http://kubernetes.io/docs/user-guide/kubectl-overview/#resource-types has the same data and is also outdated.
The patch updates these 2 lists.

make localupcluster work with RBAC enabled
When `ENABLE_RBAC=true` is set to true, `local-up-cluster` fails because it can't reach the endpoint (get a 403). This changes to an endpoint that the default policy allows anyone to see.

make kubeadm version use kubeadmutil
What this PR does / why we need it:
this PR makes sure `kubeadmutil.CheckErr()` other than `cmdutil.CheckErr()` is called in `kubeadm version` subcommand.
in `version.go`, `RunVersion()` function only returns `nil`, `kubeadmutil.CheckErr()` is enough for this

Better kubectl run validations
Adds more validations to flags that must be mutually exclusive in `kubectl run`. For example, `--dry-run` must not be used with `--attach`, `--stdin` or `--tty`. Adds unit tests for these new validations and some previously existing ones.

**What this PR does / why we need it**: pre-flight check hostname to ensure kubelet can launch static pods like kube-apiserver/kube-controller-manager
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
**Special notes for your reviewer**:
# what is the influence of this issue?
kubelet will not create api server and kcm pod if your hostname is uncorrect. It complain the config files in "/etc/kubernetes/manifests" are invlid.
# how to reproduce this issue?
change your hostname by `hostnamectl set-hostname vm_81_12_centos`. then run `kubeadm init`. you will get this error log from kubelet:
```log
Oct 27 11:12:57 vm_81_12_centos kubelet: I1027 11:12:57.279458 2695 file.go:123] Can't process config file "/etc/kubernetes/manifests/kube-controller-manager.json": invalid pod: [metadata.name: Invalid value: "kube-controller-manager-vm_81_12_centos": must match the regex [a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)* (e.g. 'example.com') spec.nodeName: Invalid value: "vm_81_12_centos": must match the regex [a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)* (e.g. 'example.com')]
```
# where the error comes from in the code?
`pkg/kubelet/config/file.go:144 sourceFile:extractFromDir`
```go
func (s *sourceFile) extractFromDir(name string) ([]*api.Pod, error) {
dirents, err := filepath.Glob(filepath.Join(name, "[^.]*"))
if err != nil {
return nil, fmt.Errorf("glob failed: %v", err)
}
pods := make([]*api.Pod, 0)
if len(dirents) == 0 {
return pods, nil
}
sort.Strings(dirents)
for _, path := range dirents {
statInfo, err := os.Stat(path)
if err != nil {
glog.V(1).Infof("Can't get metadata for %q: %v", path, err)
continue
}
switch {
case statInfo.Mode().IsDir():
glog.V(1).Infof("Not recursing into config path %q", path)
case statInfo.Mode().IsRegular():
pod, err := s.extractFromFile(path)
if err != nil {
--> glog.V(1).Infof("Can't process config file %q: %v", path, err)
} else {
pods = append(pods, pod)
}
default:
glog.V(1).Infof("Config path %q is not a directory or file: %v", path, statInfo.Mode())
}
}
return pods, nil
}
```
# how to fix it?
1. change hostname by `hostnamectl set-hostname <right host name>` or
2. add `hostnameOverride` config. If hostnameOverride is set, then kubelet will use this value instead of system hostname.

fixed some issues with kubectl set resources
when using kubectl set resources it resets all resource fields that are not being set.
for example
# kubectl set resources deployments nginx --limits=cpu=100m
followed by
# kubectl set resources deployments nginx --limits=memory=256Mi
would result in the nginx deployment only limiting memory at 256Mi with the previous
limit placed on the cpu being wiped out. This behavior is corrected so that each invocation
only modifies fields set in that command and changed the testing so that the desired behavior
is checked.
Also a typo:
you must specify an update to requests or limits or (in the form of --requests/--limits)
corrected to
you must specify an update to requests or limits (in the form of --requests/--limits)
Implemented both the dry run and local flags.
Added test cases to show that both flags are operating as intended.
Removed the print statement "running in local mode" as in PR#35112

Remove Job also from .status.active for Replace strategy
When iterating over list of Jobs we're removing each of them when strategy is replace. Unfortunately, the job reference was not removed from `.status.active` which cause the controller trying to remove it once again during next run and failed removing what was already removed during previous run. This was cause by not removing the reference previously. This PR fixes that and cleans logs a bit, in that controller.

Verify and update client-go staging area for every PR
We need to keep the staging area up-to-date to prevent PRs from breaking client-go.
It's marked as "WIP" because we need to decide the [versioning strategy](https://github.com/kubernetes/client-go/issues/9) for client-go first. This PR contains breaking changes for client-go.
This is blocking #29934 and potentially #34441

Fix#35237
This PR make versioned clientset to include multiple versions of a group. Currently only `batch` has `v1` and `v2alpha1`. The clientset interface now looks like:
```go
BatchV2alpha1() v2alpha1batch.BatchV2alpha1Interface
BatchV1() v1batch.BatchV1Interface
// Deprecated: please explicitly pick a version if possible.
Batch() v1batch.BatchV1Interface
