Add missing expansion files to versioned clientset
I copied the expansion functions that only existed in the internalclientset to release_1_5.
Most changes are mechanical. This is needed for migrating k8s to use versioned clientset, so I add the 1.5 milestone.

Switch DisruptionBudget api from bool to int allowed disruptions [only v1beta1]
Continuation of #34546. Apparently it there is some bug that prevents us from having 2 different incompatibile version of API in integration tests. So in this PR v1alpha1 is removed until testing infrastructure is fixed.
Base PR comment:
Currently there is a single bool in disruption budget api that denotes whether 1 pod can be deleted or not. Every time a pod is deleted the apiserver filps the bool to false and the disruptionbudget controller sets it to true if more deletions are allowed. This works but it is far from optimal when the user wants to delete multiple pods (for example, by decreasing replicaset size from 10000 to 8000).
This PR adds a new api version v1beta1 and changes bool to int which contains a number of pods that can be deleted at once.

always allow decoding of status when returned from the API
`unversioned.Status` should be able to come back from any API version and still be properly decoded. This doesn't happen today by default.
@smarterclayton Our projectrequest endpoint returns a `Status` object on a 200 return from list to indicate everything went well. This (or something like it) is needed to make the API accepted by `kubectl`. Alternatively, we change the API to return a different (still not a `Project`) value from list, which still feels wrong.

clean up client version negotiation to handle no legacy API
Version negotiation fails if the legacy API endpoint isn't available.
This tightens up the negotiation interface based to more clearly express what each stage is doing and what the constraints on negotiation are. This is needed to speak to generic API servers.

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.
