make easy validation admission plugins into validators
This switches "easy" admission plugins that need to be validators to be validators. I also did one simple plugin to do both mutation and validation for practice.

@jiayingz Sorry, there is something wrong with my branch in #51895. And I think the existing comments in the PR might be too long for others to view. So I closed it and opened the new one, as we have basically reach an agreement on the implement :)
I have covered the functionality and unit test part here, and would set about the e2e part ASAP

admission: wire through validating-only admission
Based on https://github.com/kubernetes/kubernetes/pull/54232.
This is important and required for beta because it affects the shape of the webhook admission plugins that are going to be produced and is needed to make sure that our existing chain continues to properly verify and protect the API objects based on their final state after webhook admission mutators run.
We discussed this in the October 11 API machinery call with @erictune and @caesarxuchao and we agreed to do this as a requirement for beta. See this part of the recording: https://www.youtube.com/watch?v=mrgDPHyr4VY#t=325 .

Allow override of cluster level (default, whitelist) tolerations by namespace level empty (default, whitelist) tolerations.
Currently In PodTolerationRestriction admission plugin, if namespace level default and whitelist of tolerations are nil or empty, they do not override cluster level default and whitelist tolerations.
This PR fixes the plugin to not override cluster level tolerations only when namespace level toleration are nil. IOW, if namespace level toleration are empty, they override cluster level tolerations. To be more clear, if following annotations are set to empty, they override cluster level tolerations.
```
scheduler.alpha.kubernetes.io/defaultTolerations : ""
scheduler.alpha.kubernetes.io/tolerationsWhitelist: ""
```
This behavior is inline with PodNodeSelector admission plugin too.
@sjenning @derekwaynecarr
**Release Note**:
```release-note
In PodTolerationRestriction admisson plugin, if namespace level tolerations are empty, now they override cluster level tolerations.
```

admission: unify plugin constructors
It's common in Go to return the actual object in constructors, not **one interface**
it implements. This allows us to implement multiple interfaces, but only have
one constructor. As having private types in constructors, we export all plugin structs, of course with private fields.
Note: super interfaces do not work if there are overlapping methods.

Optimize Repeated registration of AlgorithmProvider when ApplyFeatureGates
**What this PR does / why we need it**:
modified ApplyFeatureGates() just add/del features, cancel the register of all AlgorithmProvider.
there is Repeated registration of all AlgorithmProvider when ApplyFeatureGates() runs;
AlgorithmProvider have already registered when package defaults loaded;
I think ApplyFeatureGates() is just add/del features, it needn't register all AlgorithmProvider again

Ability to do object count quota for all namespaced resources
**What this PR does / why we need it**:
- Defines syntax for generic object count quota `count/<resource>.<group>`
- Migrates existing objects to support new syntax with old syntax
- Adds support to quota all standard namespace resources
- Updates the controller to do discovery and replenishment on those resources
- Updates unit tests
- Tweaks admission configuration around quota
- Add e2e test for replicasets (demonstrate dynamic generic counting)
```
$ kubectl create quota test --hard=count/deployments.extensions=2,count/replicasets.extensions=4,count/pods=3,count/secrets=4
resourcequota "test" created
$ kubectl run nginx --image=nginx --replicas=2
$ kubectl describe quota
Name: test
Namespace: default
Resource Used Hard
-------- ---- ----
count/deployments.extensions 1 2
count/pods 2 3
count/replicasets.extensions 1 4
count/secrets 1 4
```
**Special notes for your reviewer**:
- simple object count quotas no longer require writing code
- deferring support for custom resources pending investigation about how to share caches with garbage collector. in addition, i would like to see how this integrates with downstream quota usage in openshift.
**Release note**:
```release-note
Object count quotas supported on all standard resources using `count/<resource>.<group>` syntax
```

Fix range for min value in imagepolicy admission
**What this PR does / why we need it**:
This makes the range for imagepolicy admission work properly. Currently if we specify `1s` for the value of `AllowTTL` or `DenyTTL` in the configuration yaml, we get a message like the following:
```
Error: failed to initialize plugins: Couldn't init admission plugin "ImagePolicyWebhook": valid value is between 1s and 30m0s, got 1s
```
This is due to a wrong comparison which is fixed in this PR. The rest of the PR just adds tests for this behaviour.
