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.

Set done to true & return error if RestartPolicy not Always in test framework

Found a small issue with https://github.com/kubernetes/kubernetes/pull/34632, it returns an error if the RestartPolicy is not Always, but the user will never see it because done isn't set to true & they will timeout instead.

Fix potential panic in namespace controller when rapidly create/delet…

Fixes https://github.com/kubernetes/kubernetes/issues/33676

The theory is this could occur in either of the following scenarios:

1. HA environment where a GET to a different API server than what the WATCH was read from
1. In a many controller scenario (i.e. where multiple finalizers participate), a namespace that is created and deleted with the same name could trip up the other namespace controller to see a namespace with the same name that was not actually in a delete state.  Added checks to verify uid matches across retry operations.

This should avoid spamming build-log.txt with messages like:

    perl: warning: Falling back to the standard locale ("C").

OSX has shasum but not sha1sum, which is part of GNU coreutils.

First pass at CRI stream server library implementation

This is a first pass at implementing a library for serving attach/exec/portforward calls from a CRI shim process as discussed in [CRI Streaming Requests](https://docs.google.com/document/d/1OE_QoInPlVCK9rMAx9aybRmgFiVjHpJCHI9LrfdNM_s/edit#).

Remaining library work:
- implement authn/z
- implement `stayUp=false`, a.k.a. auto-stop the server once all connections are closed

Adding cascading deletion support to federated namespaces

Ref https://github.com/kubernetes/kubernetes/issues/33612

With this change, whenever a federated namespace is deleted with `DeleteOptions.OrphanDependents = false`, then federation namespace controller first deletes the corresponding namespaces from all underlying clusters before deleting the federated namespace.

```release-note
Adding support for DeleteOptions.OrphanDependents for federated namespaces. Setting it to false while deleting a federated namespace also deletes the corresponding namespace from all registered clusters.

This restores all the code but turns off the boolean that allows unsafe. Allows further iteration.

This is a simpler version of the revert that preserves the other improvements to the code.

Make get-kube.sh smarter when choosing if it should download

The #19404 fix for #15197 doesn't work very well when this script is used in CI

Since our kubernetes release tarballs are always named `kubernetes.tar.gz`, checking timestamps alone won't guarantee we do the right thing. If we're trying to extract a different release than the version currently downloaded, both `curl` and `wget` will just use the preexisting version.

My change makes the caching a bit more explicit; we look inside the kubernetes tarball for the `version` file and compare that to the release requested.

I've also added some code to automatically delete the preexisting `kubernetes/` directory so that we don't get into a weird state with multiple versions extracted into the same root.

This is a lot of shell, and I've tested the various branches manually, but we definitely need a better way to automate testing this (or simplify/remove some of the functionality).
