Removal of KubeletConfigFile feature gate: Step 1
This feature gate was redundant with the `--config` flag, which already
enables/disables loading Kubelet config from a file.
Since the gate guarded an alpha feature, removing it is not a violation
of our API guidelines.
Some stuff in `kubernetes/test-infra` currently sets the gate,
so removing will be a 3 step process:
1. This PR, which makes the gate a no-op.
2. Stop setting the gate in `kubernetes/test-infra`.
3. Completely remove the gate (this PR will get the release note).

remove duplicated check of device path in aws attacher
**What this PR does / why we need it**:
The `devicePath` parameter is already validated in this [code](b7100f1ee7/pkg/volume/aws_ebs/attacher.go (L158)), so no need to check it again in the `for loop` as it won't be modified.

Add a metric to track usage of inflight request limit.
This one is tricky. The goal is to know how 'loaded' given apiserver is before we start dropping the load, to so we need to somehow expose 'fullness' of channels.
Sadly this metric is pretty volatile so it's not clear how to do this correctly. I decided to do pre-aggregation to smoothen the metric a bit. In the current implementation the metric publishes maximum "usage" of the inflight is previous second.
If you have any ideas please share.

Promote Statefulset controller and its e2e tests to use apps/v1
**What this PR does / why we need it**:

Fixes # https://github.com/kubernetes/kubernetes/issues/55714
**Special notes for your reviewer**:
* Listerexpansion for v1 `k8s.io/client-go/listers/apps/v1` (was recently done for v1beta2)
* `v1beta2` && `v1` had `ObservedGeneration` as `int64` where as `v1beta1` and rest of the code (including conversion) is expecting `ObservedGeneration` to be `*int64`
```
type StatefulSetStatus struct {
// observedGeneration is the most recent generation observed for this StatefulSet. It corresponds to the
// StatefulSet's generation, which is updated on mutation by the API Server.
// +optional
ObservedGeneration int64 `json:"observedGeneration,omitempty" protobuf:"varint,1,opt,name=observedGeneration"`
```
* for kubectl's `rollback` and `history` commands a couple functions have been duplicated to allow us to use `v1` version instead of `v1beta1` for statefulsets, while the older functions are still used by other controllers.
We should be able to remove these duplicates once all the controllers are moved.
If this aligns with the plan then i could move other controllers too.

Resource version parsing should all be in one place
This is 100% refactoring that ought to be a no-op at run time. It puts resource version parsing in a single file. Doing this because I want to follow up with a change which will make it obvious to users of the system our rules about resource version. Don't want to mix that with this refactor (on the off chance it gets rolled back).

**What this PR does / why we need it**:
Add bootstrapping logic and Context for vSphere tests. This context can be utilized to hold information like node-vsphere mapping, which needs to be initialized only once per test suit run.

Set pids limit at pod level
**What this PR does / why we need it**:
Add a new Alpha Feature to set a maximum number of pids per Pod.
This is to allow the use case where cluster administrators wish
to limit the pids consumed per pod (example when running a CI system).
By default, we do not set any maximum limit, If an administrator wants
to enable this, they should enable `SupportPodPidsLimit=true` in the
`--feature-gates=` parameter to kubelet and specify the limit using the
`--pod-max-pids` parameter.
The limit set is the total count of all processes running in all
containers in the pod.
