Fix RC/RS conversion

This fixes some round-trip information loss when representing an RC as an RS. I want to use these conversions in #49429 to eliminate the maintenance burden of duplicated RC code.

decode admission responses into a fresh object

Something about the way the admission request object is built causes decoding into back into it to fail with 

```
W1013 14:10:42.457423    2960 admission.go:185] rejected by webhook namespacereservations.admission.online.openshift.io/apis/admission.online.openshift.io/v1alpha1/namespacereservations &{%!t(string=namespacereservations.admission.online.openshift.io/apis/admission.online.openshift.io/v1alpha1/namespacereservations) %!t(*errors.errorString=&{reflect.Value.Addr of unaddressable value})}: failed calling admission webhook "namespacereservations.admission.online.openshift.io/apis/admission.online.openshift.io/v1alpha1/namespacereservations": reflect.Value.Addr of unaddressable value
```

This simply creates a fresh object to decode into, which works fine for our usage and makes it possible to actually have the webhook call out to something.

pkg/api: extract Scheme/Registry/Codecs into pkg/api/legacyscheme

This serves as

- a preparation for the pkg/api->pkg/apis/core move
- and makes the dependency to the scheme explicit when vizualizing
  left depenncies.

The later helps with our our efforts to split up the monolithic repo
into self-contained sub-repos, e.g. for kubectl, controller-manager
and kube-apiserver in the future.

Always retry connection reset error in webhook

Fixes https://github.com/kubernetes/kubernetes/issues/52909

Audit logging uses webhook to send events to the backend and currently even a little blip in networking can cause several hundreds of events to be lost. This PR adds an additional check, that is similar to [the one in the rest package](https://github.com/kubernetes/kubernetes/blob/master/staging/src/k8s.io/client-go/rest/request.go#L657), but ignores the fact that the request is not GET and always retries "Connection reset by peers" error.

```release-note
Webhook always retries connection reset error.

fix PV Recycle issue when running on multi-arch

**What this PR does / why we need it**:
Currently PV Recycle uses image `gcr.io/google_containers/busybox`, which is an amd64 image, not applied for multi-arch , to start pod `"pv-recycler"`. For other non-x86 platforms, like `ppc64le` and `arm64`, the pod cannot get started due to the busybox image.

refactor pd.go for future tests

**What this PR does / why we need it**:
Refactored _test/e2e/storage/pd.go_ so that it will be easier to add new tests, which I plan on doing to address issue 52676
1. Condenses 8 `It` blocks into 3 table driven tests.
2. Adds several `By` descriptions and `Logf` messages.
3. provides more consistent formatting and messages.

**Special notes for your reviewer**:
The diff is large but mostly I've not altered any test. The one semantic change I made was to remove the call to verify a write to a PD when, in fact, nothing had been written yet. This was essentially a no-op since the verify code returned immediately if the passed-in map was empty (which it was since nothing had been written).

Remove dangling shell functions

**What this PR does / why we need it**:

This is clean up for shell functionality that was left over from when something was first added and subsequently removed, but didn't include cleaning up all of the logic they references.

**Special notes for your reviewer**:

I traced back the functions to when they were added and had their references removed, so I thought I'd share that for context:

* `kube::golang::current_platform` was added in 5d33ce46, but never ended up being used. My understanding is that this is due to having more or less the same logic available in `kube::golang::host_platform`, which is what's being used.

* `kube::util::gen-analytics` was added in 553f9f82 and had the use of it removed in 902ffd53 when docs 

* `kube::util::analytics-link` was added in 553f9f82 and had the use of it removed in ffcc6cad

* `kube::util::get_random_port` was added in 5d08dcf8 and superseded by `kubectl proxy --port=0` in 22b43d8f

* `kube::util::test_host_port_free` was added in 5d08dcf8 and superseded by `kubectl proxy --port=0` in 22b43d8f

I should also note that [`kube::golang::unset_platform_envs()`](https://github.com/kubernetes/kubernetes/blob/e8e72a44444d9ded58bcba13d650c98dab2cb465/hack/lib/golang.sh#L301-L307) was introduced in 5d33ce46 and is currently unused, but was referenced in 9848d6cc and subsequently removed in 38690ff7. If that's something worth including here, I'd be happy to add that also.
