return err on `kubectl run --image` with invalid value
When running `kubectl run <configname> --image="Invalid$$%ImageValue%%__"`, a configuration is successfully created with an image name that is not a valid value for an image reference.
This patch validates that the image name is a valid image reference, and returns an error before creating a config if an invalid value is passed.
`$ kubectl run test --image="Invalid__%imagename"`
```
error: Invalid image name "Invalid__%imagename": invalid reference format
```

Basic audit log
Fixes#2203 by introducing simple audit logging, including the information about impersonation. We currently have something identical in openshift, but I'm open to any suggestions. Sample logs look like that:
as `<self>`:
```
AUDIT: id="75114bb5-970a-47d5-a5f1-1e99cea0574c" ip="127.0.0.1" method="GET" user="test-admin" as="<self>" namespace="openshift" uri="/api/v1/namespaces/openshift/pods/python"
AUDIT: id="75114bb5-970a-47d5-a5f1-1e99cea0574c" response=200
```
as user:
```
AUDIT: id="b0a443ae-f7d8-408c-a355-eb9501fd5c59" ip="192.168.121.118" method="GET" user="system:admin" as="test-admin" namespace="openshift" uri="/api/v1/namespaces/openshift/pods/python"
AUDIT: id="b0a443ae-f7d8-408c-a355-eb9501fd5c59" response=200
```
```release-note
* Add basic audit logging
```

Let kubectl delete rc and rs with DeleteOptions.OrphanDependents=false
so that when the garbage collector is enabled, RC and RS are deleted immediately without waiting for the garbage collector to orphan the pods.
There is no user visible changes, so we don't need a release note.

Fix code generators-- make scheme building composable
I needed to make some changes to make my other refactoring possible and this got rather large.
We now provide a "SchemeBuilder" to help all of the api packages provide their scheme-building functions (addKnownTypes and friends) in a standardized way. This also allows generated deepcopies & conversions to be entirely self contained, the project will now build without them being present (as they can add themselves to the SchemeBuilder). (Although if you actually build without them, you will get reduced performance!)
Previously, there was no way to construct your own runtime.Scheme (e.g., to test), you had to use the api.Scheme object, which has all sorts of non-hermetic cruft in it. Now you can get everything from a package by calling the scheme builder's AddToScheme, including the generated functions, if they are present.
Next steps are to allow for declaring dependencies, and to standardize the registration & install code. (#25434)

the observed usage should match those that have hard constraints
in the sync process, the quota will be replenished, the new observed usage will be sumed from each evaluator, if the previousUsed set is not be cleared, the new usage will be dirty, maybe some unusage resource still in , as the code below
newUsage = quota.Mask(newUsage, matchedResources)
for key, value := range newUsage {
usage.Status.Used[key] = value
}
so i think here shoul not set value previousUsed

Quota admission errors if usage is negative
If quota observes negative usage for an artifact, that artifact could game the quota system.
This adds a global check in the quota system to catch this scenario for all evaluators.

```release-note
Added `golint` for pkg/security/podsecuritypolicy/capabilities` along with validation.
```
[]()
This is a POC to start enabling `golint` checks on a per-package basis, we did this on the docker project and it was a great way for new contributors to help and it benefits the project overall. All they have to do is add the package they fixed to the bash array in `hack/verify-golint.sh` and fix all the lint errors.
Eventually when all the packages have been fixed we can change the function to `find_files`. Or something based off which files are changed in a patch set to verify `golint`.
Now I used this specific package as the POC because I wanted to show the downside of this changing the api of the package.
Most of the times this arose in docker/docker we decided that if someone wasn't importing their deps locally then it was their loss, but I'm not sure if you all will agree.

check validation with no apps client in kubectl util factory
autoscaling client already exist:
if c.c.AutoscalingClient == nil {
return errors.New("unable to validate: no autoscaling client")
so following autoscaling client should be apps client:
if c.c.AppsClient == nil {
return errors.New("unable to validate: no autoscaling client")

[Kubelet] Rename `--config` to `--pod-manifest-path`. `--config` is deprecated.
This field holds the location of a manifest file or directory of manifest
files for pods the Kubelet is supposed to run. The name of the field
should reflect that purpose. I didn't change the flag name because that
API should remain stable.

[GarbageCollector] measure latency
First commit is #27600.
In e2e tests, I measure the average time an item spend in the eventQueue(~1.5 ms), dirtyQueue(~13ms), and orphanQueue(~37ms). There is no stress test in e2e yet, so the number may not be useful.

Simplify canonical element term in deepcopy
Replace the old functional canonical element term in deepcopy registration with direct struct instantiation.
The old way was an artifact of non-uniform pointer/non-pointer types in the signature of deepcopy function. Since we changed that to always be a pointer, we can simplify the code.
