Complete the rewrite the policy option compatibility tests,
rewriting the tests which check compatibility
between the `full-pcpus-only` and `distribute-cpus-across-numa`.
All testcases are preserved.

add missing metric about uncore / L3 / Last-Level cache alignment,
plus its e2e tests.
Exposing uncore alignment requires a bit of refactoring in the static
policy implementation because, differently from full PCPUs alignment
and NUMA alignment, can't be easily and safely inferred by construction.
The main reason for this is that uncore cache alignment is preferred,
not mandatory, thus the cpu allocator can legally use cross-uncore
allocation. Because of that, the final cpuset union step can
create a final cpuset which is not uncore-aligned even though all
its parts are uncore-aligned.
The safest way seems thus to run just a final uncore-alignment check
once the final cpuset is computed.

add (admittedly pretty crude) CPU allocatable check.
A more incisive refactoring is needed, but we need
to unbreak CI first, so this seems the minimal decently clean test.

Our CI machines happen to have 1 fully allocatable CPU for test workloads.
This is really, really the minimal amount. But still should be sufficient for the tests to run
the tests; the CFS quota pod, however, does create a series of pods (at time of writing, 6)
and does the cleanup only at the very end the end. This means pods
requiring resources accumulate on the CI machine node.
The fix implemented here is to just clean up after each subcase.
Doing so the cpu test footprint is equal to the higher requirement (say, 1000 millicores) vs
the sum of all the subcases requirements.
Doing like this doesn't change the test behavior, and make it possible
to run it on very barebones machines.
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.
We use the label definitions in CRI-O, means we now make them public to
stop vendoring/copying this part of Kubernetes.

All usage of builder pattern is convertible to cpuset.New()
with the same or fewer lines of code.
Migrate Builder.Add to a private method of CPUSet, with a comment
that it is only intended for internal use to preserve immutable
propoerty of the exported interface.
This also removes 'require' library dependency, which avoids
non-standard library usage.
In 'set', conversions to slice are done also, but with different names:
ToSliceNoSort() -> UnsortedList()
ToSlice() -> List()
Reimplement List() in terms of UnsortedList to save some duplication.
Removes exit/fatal from cpuset library.
Usage in podresources test was not necessary.
Library reference in cpu_manager_test was moved to a local function, and
converted to use e2e test framework error catching.
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.
One of the cpumanager tests doesn't remove the pod
that got created during the test.
This causes pollution of other tests and failures
from time to time (depends on the test execution order).
In order to defalke the tests, we should delete the pod
and wait for it to be completely remove.

This patch makes the CRI `v1` API the new project-wide default version.
To allow backwards compatibility, a fallback to `v1alpha2` has been added
as well. This fallback can either used by automatically determined by

We graduate the `CPUManagerPolicyOptions` feature to beta
in the 1.23 cycle, and we add new experimental feature gates
to guard new options which are planned in the 1.23 and in the
following cycles.
We introduce additional feature gate called `CPUManagerPolicyAlphaOptions` and
`CPUManagerPolicyBetaOptions`. The basic idea is to avoid the
cumbersome process of adding a feature gate for each option, and to have
feature gates which track the maturity level of _groups_ of options.
Besides this change, the graduation process, and the process in general,
for adding new policy options is still unchanged.
The `full-pcpus-only` option added in the 1.22 cycle is intentionally
moved into the beta policy options

Add e2e tests to cover the basic flows for the `full-pcpus-only` option:
negative flow to ensure rejection with proper error message, and
positive flow to verify the actual cpu allocation.

The CPUManager graduated to beta a while ago (k8s 1.10?)
so let's get rid of the obsolete Alpha tag on its e2e tests.
