4d5264fb0b logging benchmark: support slog 
Replacing zapr with slog as JSON implementation can be benchmarked by replacing
"false" with "true" and rerunning. However, slog is slower:

099f26296b integration test for cloud provider 
very simple tests to check that the node controllers removes the taint.

Test will be used later for add more coverage without having to depend
on e2e tests for validating complex scenarios and combinations of flags
and controllers.

b584b87a94 kube-controller-manager: readjust log verbosity 
- Increase the global level for broadcaster's logging to 3 so that users can ignore event messages by lowering the logging level. It reduces information noise.
- Making sure the context is properly injected into the broadcaster, this will allow the -v flag value to be used also in that broadcaster, rather than the above global value.
- test: use cancellation from ktesting
- golangci-hints: checked error return value

1ecd4053de ktesting: skip timing check in unit test 
Extending the duration and the allowed delta in f6682370b1 was still not enough
to make the unit test run reliably in pull-kubernetes-unit.

Now it uses the original, stricter timing again, but only when run locally. In
Prow (detected by checking the "CI" env variable), the duration check is
skipped.

See https://go.dev/blog/deadcode for an introduction.

This removes everything that was reported as dead code for

da8ffcd1dc Switch 'ContainerCheckpoint' from Alpha to Beta 
* Forensic Container Checkpointing as described in KEP 2008 moves from
   Alpha to Beta. This is corresponding code change.

 * Adapt e2e test to handle
   '(rpc error: code = Unimplemented desc = unknown method CheckpointContainer'
   and
   '(rpc error: code = Unimplemented desc = method CheckpointContainer not implemented)'
   and
   '(rpc error: code = Unknown desc = checkpoint/restore support not available)'
   One error message is if the CRI implementation does
   not implement the CRI RPC (too old) and the second is
   if the CRI implementation does explicitly not support the feature.
   The third error message can be seen if the container engine
   explicitly disabled the checkpoint/restore support,

 * As described in the corresponding KEP 2008 explicitly test for
   disabled functionality.

 * Extended test to look for the checkpoint kubelet metric.

 * Extended test to look for the CRI error metric.

 *  Add separate sub-resource permission to control permissions on
    the checkpoint kubelet API endpoint

cb3180950e dra e2e: fix stack unwinding in helper function 
When failing inside the `ginkgo.By` callback function, skipping intermediate
stack frames didn't work properly because `ginkgo.By` itself and other internal
code is also on the stack.

To fix this, the code which can fail now runs outside of such a
callback. That's not a big loss, the only advantage of the callback was getting
timing statistics from Ginkgo which weren't used in practice.
