when a test is verifying a container has restarted, we use a continually exiting
container. Not verifying the number of restarts is less than (rather than equal) introduces
a race between the container restarting and the status observation.

in general, the rewritten e2e cpumanager test assume cgroup v2.
A limited set of these may be updated to work also with the
obsolete and declining cgroup v1, but these need to be reviewed
on test-by-test matter.
To fix test failures, we add a top level require for cgroup v2,
skipping otherwise. This will fix the red lanes while we review
the testcases and the deprecation plan of the other tests.

The package is unmaintained, and the tests don't rely on the
functionality it provides on top of Golang errors (stack traces).

The PR https://github.com/kubernetes/kubernetes/pull/130274 rewrote the
cpumanager tests assuming there are always at least 4 online CPUs,
adding checks for the tests which require more.
We still have, and likely we will have for the time being, lanes
which run on machines with 2 online CPUs.
Thus, every test which either reserve cpus (--reserved-cpus) or run
pods with exclusive CPU allocation must declare the requisites
and skip if the machine don't provide them.

Adds a DRA e2e_node test to verify that the kubelet plugin manager
retries plugin registration when the GetInfo call fails, and
successfully registers the plugin once GetInfo succeeds.
This ensures correct recovery and registration behavior for
DRA plugins in failure scenarios.
We only need one special "DynamicResourceAllocation" feature for the optional
node support of DRA (plugin registration, CDI support in the container
runtime). For individual features, the automatic labeling through
WithFeatureGate is sufficient.
To find DRA-related tests in a label filter, instead of plain-text "DRA" a
"DRA" label now gets added.
This change depends on an update of the DRA jobs.
rewrite the tests porting to the new layout and utilities.
We may add more cases and better integration in the future.

now that we have a minimal BeforeEach (and let's keep it this way)
we can factor out the reservedCPUs setting, since it's the same
code for each testcase.

a tiny, non-nested BeforeEach (which is still OK)

rewrite tests which exercise multiple container within the
same pod. Preserve the existing testcases, add more.
Note basic coverage for mixed pods - some containers requiring
exclusive CPUs, some not, was already added with the initial batch.

We have tests which cover the case on which a pod
with a single container require multiple CPUs;
rewrite them preserving the testcases and actually
adding coverage.
Add and use stricter checks along the way.

Complete the rewrite the policy option compatibility tests,

Rewrite the policy option compatibility tests.
We start with the tests which check the compatibility
between the `full-pcpus-only` and `strict-cpu-reservation`
tests, because the former is the only GA option
at time of writing.
All testcases are preserved.

Rewrite the cpumanager tests to make use of the lessons
learned, more modern idioms, remove obsolete assumptions
and in gneeral remove all the legacy which was accumulating
over the years.
The goal is to have a simpler, flatter and more maintenable
code layout, de-entangle the net of dependency,
making the tests more robust and easier to extend.
In short, this is all about maintainability. All the testcases
will be preserved, and few other can be added along the way.
Comments in the code will explain the code layout decisions
and tradeoff, and provide a good guide to add more tests
in the future.
Special care was added in order to maximize the isolation between
tests, at cost, in selected cases of a controlled and planned
code duplication.

Passing a constant value to gomega.Consistently means that it will not re-check
while running.
Found by linter after removing the suppression rule for the check. It was
disabled earlier because of a bug in the linter.
