* 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

This changes the text registration so that tags for which the framework has a
dedicated API (features, feature gates, slow, serial, etc.) those APIs are
used.
Arbitrary, custom tags are still left in place for now.
When the e2e_node/checkpoint_container.go test was introduced no CRI
implementation supported the new CheckpointContainer RPC yet.
With the release of CRI-O 1.25 the CheckpointContainer is implemented
and the test has been extended to see if the content of the checkpoint
is as expected.
The test is skipped if the ContainerCheckpoint feature gate is disabled
or if the CRI implementation does not support the CheckpointContainer
RPC.

All code must use the context from Ginkgo when doing API calls or polling for a
change, otherwise the code would not return immediately when the test gets
aborted.
Every ginkgo callback should return immediately when a timeout occurs or the
test run manually gets aborted with CTRL-C. To do that, they must take a ctx
parameter and pass it through to all code which might block.
This is a first automated step towards that: the additional parameter got added
with
sed -i 's/\(framework.ConformanceIt\|ginkgo.It\)\(.*\)func() {$/\1\2func(ctx context.Context) {/' \
$(git grep -l -e framework.ConformanceIt -e ginkgo.It )
$GOPATH/bin/goimports -w $(git status | grep modified: | sed -e 's/.* //')
log_test.go was left unchanged.
