Stop using VersionedObject in resource.Builder, use unstructured
Remove the need for kubectl callers to distinguish between unstructured and versioned / type aware builders. The factory should create a single builder than can be set to return unstructured objects. Callers can then use one of the new helpers on `resource.Info` to convert the objects into the desired form - `Internal()` for printers, `Typed()` for external versions, and `Unstructured()` to ensure the object is in the right state. Leverages the new scheme support for unstructured conversion so that higher level callers can perform best effort conversion (get typed versions if you have them, otherwise use default behavior).
`get.go` demonstrates this by removing the previous logic that depended on the underlying scheme. Other commands are updated to be consistent.

Fix potential unexpected object mutation that can lead to data races
**What this PR does / why we need it**:
In #51526 I introduced an optimization - do a deep copy instead of to and from JSON roundtrip to convert anything that implements `runtime.Unstructured`. I just discovered that the method that is used there `UnstructuredContent()` in both `Unstructured` and `UnstructuredList` may mutate the original object.
2008750398/staging/src/k8s.io/apimachinery/pkg/apis/meta/v1/unstructured/unstructured.go (L87-L92)7c10cbc642/staging/src/k8s.io/apimachinery/pkg/apis/meta/v1/unstructured/unstructured_list.go (L58-L75)
This is problematic because previously (before #51526) there was no mutation and because this is unexpected and may lead to data races - it is bad behaviour to mutate original object when you just want a copy of it.
This PR fixes the issue.
Without the fix the tests I've added are failing because when comparison is done original object is not the same:
```
converter_test.go:154: Object changed, diff:
object.Object[items]:
a: []interface {}{}
b: <nil>
converter_test.go:154: Object changed, diff:
object.Object[items]:
a: []interface {}{map[string]interface {}{"kind":"Pod"}}
b: <nil>
```
However the underlying issue is not fixed here - `UnstructuredContent()` is brittle and dangerous. Method name does not imply that it mutates data when you call it. And godoc does not mention that either:
509df603b1/staging/src/k8s.io/apimachinery/pkg/runtime/interfaces.go (L233-L249)
Something needs to be done about it IMO.
Also `UnstructuredContent()` implementation in `UnstructuredList` does not implement the behaviour required by godoc in `runtime.Unstructured`.

Refactor `reconcileAutoscaler` method in hpa
**What this PR does / why we need it**:
There have been a couple of recent bugs in the "normalizing" part of the
`reconcileAutoscaler` method. This part of the code base is responsible
for, among other things, taking the suggested desired replicas based on
the metrics, ensuring it conforms to certain conditions, and updating it
if it does not. Isolate the part that converts the desired replicas
based on a given set of rules into its own function.
We are refactoring this part of the code base to make the logic simpler
and to make it easier to write unit tests.

Fixes#53728

admission/webhook: move webhook initializer into plugin
Follow-up of https://github.com/kubernetes/kubernetes/pull/55132.
Non-generic plugin intitializers should go into the admission plugin itself. No need leak that into the generic apiserver. Keeping them contained in the webhook package makes it easier (it was already possible) for extension apiservers to provide one, but we don't need to leak it into the generic plugin initializer.

It will wait until specifically told to upgrade with an action unless the configuration option require-manual-upgrade is false and then master nodes will upgrade immediately.
