* 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

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.
Since v2.45, the `stress` subcommand was added and the CI issue was fixed:

- kubernetes/kubernetes PR 123284
- kubernetes/k8s.io PR 6422

When stopping polling, the provided messages becomes the complete failure
message. This means that the code which calls gomega.StopTrying must include
the pod in the message instead of just summarizing the phase. This makes the
failure more useful.
agnhost was updated to v2.46 in PR 123258, but the image was not
published due to the failue of `post-kubernetes-push-e2e-agnhost-test-images`
(issue 123266).

Fix issue 123266

To avoid creating a manifest list with the recent version of buildx,
`--provenance=false --sbom=false` has to be specified.

Merge vishh/stress@eab4e3384b into
agnhost.
Old usage: `stress -mem-alloc-size 12Mi -mem-alloc-sleep 10s -mem-total 4Gi`
New usage: `agnhost stress --mem-alloc-size 12Mi --mem-alloc-sleep 10s --mem-total 4Gi`
This is a part of the steps to migrate from legacy Schema 1 images
(issue 123146)

Adding a doc comment for all existing items makes it more obvious that new
items should be documented more carefully. It also has the welcome side effect
that each item gets indented independently from the others.
