We only added failed plulgins, but actually this will not work unless
we make the status with a fitError because we only copy the failured plugins
to podInfo if it is a fitError

Normal binaries should never have to do this. It's not safe when there are
already some goroutines running which might do logging. Therefore the new
default is to return an error when a binary accidentally re-applies.
A few unit ensure that there are no goroutines and have to call the functions
more then once. The new ResetForTest API gets used by those to enable changing the
logging settings more than once in the same process.
Integration tests use the same code as the normal binaries. To make reuse of
that code safe, component-base/logs can be configured to silently ignore any
additional calls. This addresses data races that were found when enabling -race
for integration tests. To catch cases where the integration test does want
to modify the config, the old and new config get compared and an error is
raised when it's not the same.
To avoid having to modify all integration tests which start test servers,
reconfiguring component-base/logs is done by the test server packages.
When a pod is done, but not getting removed yet for while, then a claim that
got generated for that pod can be deleted already. This then also triggers
deallocation.
Invalid flags are detected by flag parsing, but optional arguments are just
passed through to the E2E suites. None of them support any, so rejecting them
with an error message is useful because it helps catch typos (like a missing
hyphen before a flag).
perfdash expects all data items to have the same set of labels. It then
renders drop-down buttons for each label with all values found for each
label. Previously, data items that didn't have a label didn't match any label
filter in perfdash and couldn't get selected because perfdash doesn't have
"unset" in it's drop-down menus.
To avoid that, scheduler-perf now collects all labels and then adds missing
labels with "not applicable" as value:

Because the JSON file gets written at the end of the top-level benchmark, all
data items had `BenchmarkPerfScheduling/` as prefix in the `Name` label. This
is redundant and makes it harder to see the actual name. Now that common prefix
gets removed.
CreatePod and MakePod only accepted an `isPrivileged` boolean, which made it
impossible to write tests using those helpers which work in a default
framework.Framework, because the default there is LevelRestricted.
The simple boolean gets replaced with admissionapi.Level. Passing
LevelRestricted does the same as calling e2epod.MixinRestrictedPodSecurity.
Instead of explicitly passing a constant to these modified helpers, most tests
get updated to pass f.NamespacePodSecurityLevel. This has the advantage
that if that level gets lowered in the future, tests only need to be updated in
one place.
In some cases, helpers taking client+namespace+timeouts parameters get replaced
with passing the Framework instance to get access to
f.NamespacePodSecurityEnforceLevel. These helpers don't need separate
parameters because in practice all they ever used where the values from the
Framework instance.
The namespace the crictical pod was referring to was wrong, because it
was using the generated one instead of `kube-system`. This and the
resulting test condition is now fixed.
The test seems to run only in `ci-crio-cgroupv1-node-e2e-flaky` for now.

Doing the initialization once was not good enough because it was not guaranteed
that RunCustomEtcd gets called early enough, before there are other goroutines
which use gRPC. The data race for
test/integration/apiserver.TestWatchCacheUpdatedByEtcd was:
