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.

Remove outdated parts of density test

Removed functionality is handled by RunRC in other way. Events were a proxy for checking if Pods are running. They're not needed anymore (for good few releases;)

There is no bash in etcd image, so the script needs to be "sh-friendly".

Also, few fixes to the script.

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.

Centos: download client and server tarballs instead of mondo-tarball

This should be functionally the same, except that you will download ~1/3 the bytes.

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.

Prefer sha1sum (C) to shasum (Perl).

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

    perl: warning: Setting locale failed.
    perl: warning: Please check that your locale settings:
        LANGUAGE = (unset),
        LC_ALL = (unset),
        LANG = "en_US.UTF-8"
        are supported and installed on your system.
    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.

cc @kubernetes/sig-cluster-federation @caesarxuchao


```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.

Merge but disable unsafe conversions

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.
