Avoid double decoding all client responses
Fixes#35982
The linked issue uncovered that we were always double decoding the response in restclient for get, list, update, create, and patch. That's fairly expensive, most especially for list. This PR refines the behavior of the rest client to avoid double decoding, and does so while minimizing the changes to rest client consumers.
restclient must be able to deal with multiple types of servers. Alter the behavior of restclient.Result#Raw() to not process the body on error, but instead to return the generic error (which still matches the error checking cases in api/error like IsBadRequest). If the caller uses
.Error(), .Into(), or .Get(), try decoding the body as a Status.
For older servers, continue to default apiVersion "v1" when calling restclient.Result#Error(). This was only for 1.1 servers and the extensions group, which we have since fixed.
This removes a double decode of very large objects (like LIST) - we were trying to DecodeInto status, but that ends up decoding the entire result and then throwing it away. This makes the decode behavior specific to the type of action the user wants.
```release-note
The error handling behavior of `pkg/client/restclient.Result` has changed. Calls to `Result.Raw()` will no longer parse the body, although they will still return errors that react to `pkg/api/errors.Is*()` as in previous releases. Callers of `Get()` and `Into()` will continue to receive errors that are parsed from the body if the kind and apiVersion of the body match the `Status` object.
This more closely aligns rest client as a generic RESTful client, while preserving the special Kube API extended error handling for the `Get` and `Into` methods (which most Kube clients use).

Add tooling to generate listers
Add lister-gen tool to auto-generate listers. So far this PR only demonstrates replacing the manually-written `StoreToLimitRangeLister` with the generated `LimitRangeLister`, as it's a small and easy swap.

Verify and update client-go staging area for every PR
We need to keep the staging area up-to-date to prevent PRs from breaking client-go.
It's marked as "WIP" because we need to decide the [versioning strategy](https://github.com/kubernetes/client-go/issues/9) for client-go first. This PR contains breaking changes for client-go.
This is blocking #29934 and potentially #34441

convert SA controller to shared informers
convert the SA controller to shared informer + workqueue.
I think one of @derekwaynecarr @ncdc or @liggitt
Alter how runtime.SerializeInfo is represented to simplify negotiation
and reduce the need to allocate during negotiation. Simplify the dynamic
client's logic around negotiating type. Add more tests for media type
handling where necessary.

remove the non-generated client
Removes the non-generated client from kube. The package has a few methods left, but nothing that needs updating when adding new groups.

Most normal codec use should perform defaulting. DirectCodecs should not
perform defaulting. Update the defaulting_test to fuzz the list of known
defaulters. Use the new versioning.NewDefaultingCodec() method.

add optional mutation checks for shared informer cache
We need to make sure that no one is mutating caches if they're using a shared informer. It is important that whatever is tracking those changes gets the object *before* anyone else possibly could.
This adds the ability to track the original objects in the cache and their current values. Go doesn't have an exit hook or a way to say "wait for non-daemon go-funcs to complete before exit", so this runs a gofunc on a loop that can panic the entire process. It's gated behind an env var.
@derekwaynecarr did I get the right spots to make sure that e2e runs with this flag?
