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.
framework.SIGDescribe is better because:
- Ginkgo uses the source code location of the test, not of the wrapper,
when reporting progress.
- Additional annotations can be passed.
To make this a drop-in replacement, framework.SIGDescribe generates a function
that can be used instead of the former SIGDescribe functions.
windows.SIGDescribe contained some additional code to ensure that tests are
skipped when not running with a suitable node OS. This gets moved into a
separate wrapper generator, to allow using framework.SIGDescribe as intended.
To ensure that all callers were modified, the windows.sigDescribe isn't
exported anymore (wasn't necessary in the first place!).
The recently introduced failure handling in ExpectNoError depends on error
wrapping: if an error prefix gets added with `fmt.Errorf("foo: %v", err)`, then
ExpectNoError cannot detect that the root cause is an assertion failure and
then will add another useless "unexpected error" prefix and will not dump the
additional failure information (currently the backtrace inside the E2E
framework).
Instead of manually deciding on a case-by-case basis where %w is needed, all
error wrapping was updated automatically with
sed -i "s/fmt.Errorf\(.*\): '*\(%s\|%v\)'*\",\(.* err)\)/fmt.Errorf\1: %w\",\3/" $(git grep -l 'fmt.Errorf' test/e2e*)
This may be unnecessary in some cases, but it's not wrong.

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.
ginkgo.DeferCleanup has multiple advantages:
- The cleanup operation can get registered if and only if needed.
- No need to return a cleanup function that the caller must invoke.
- Automatically determines whether a context is needed, which will
simplify the introduction of context parameters.
- Ginkgo's timeline shows when it executes the cleanup operation.
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.

This add e2e test for HPA ContainerResource metrics. This add test to cover two scenarios
1. Scale up on a busy application with an idle sidecar container
2. Do not scale up on a busy sidecar with an idle application.

The MetricsGrabber itself knows now whether it supports each
component. The checks inside the tests therefore are redundant at best
or worse, they are wrong: for example, on a KinD cluster the check for
"has master node registered" failed and metrics grabbing from
scheduler and controller manager were skipped unnecessarily.
The MetricsGrabber checked whether a component supported metrics
grabbing, but then tests didn't have an API to use the result of that
check. Because metrics grabbing is an optional debug feature, tests
must skip checks that depend on metrics data or, when the entire
test is about metrics data, skip the test.
This is now supported with a special error that gets wrapped and
returned by the individual Grab functions.
The previous approach with grabbing via a nginx proxy had some
drawbacks:
- it did not work when the pods only listened on localhost (as
configured by kubeadm) and the proxy got deployed on a different
node
- starting the proxy raced with starting the pods, causing
sporadic test failures because the proxy was not set up
properly unless it saw all pods when starting the e2e.test
- the proxy was always started, whether it is needed or not
- the proxy was left running after a test and then the next
test run triggered potentially confusing messages when
it failed to create objects for the proxy
The new approach is similar to "kubectl port-forward" + "kubectl get
--raw". It uses the port forwarding feature to establish a TCP
connection via a custom dialer, then lets client-go handle TLS and
credentials.
Somehow verifying the server certificate did not work. As this
shouldn't be a big concern for E2E testing, certificate checking gets
disabled on the client side instead of investigating this further.
As a part of cleaning up inactive members (those with no activity within
the past 18 months) from OWNERS files, this commit moves fabxc from an
approver to an emeritus_approver.
