KEP-2593 proposed to expand the existing node-ipam controller
to be configurable via a ClusterCIDR objects, however, there
were reasonable doubts on the SIG about the feature and after
several months of dicussions we decided to not move forward
with the KEP intree, hence, we are going to remove the existing
code, that is still in alpha.

* Add warning handler callback function in shortcut expander
Currently, errors in client-go are propagated back to the callers via
function returns. However, there is no elegant way for just warning users.
For example, when user wants to get a resource with it's short name format
and if there are multiple resources belonging to this short name, we need to
warn user about this ambugity which one is picked and which ones are discarded.
Not only to overcome this particular case mentioned above, but also propose a
way for the possible warnings in the future, this commit adds a warningHandler
callback function in shortcutExpander.
* Add warningPrinter functionality in ConfigFlags
ConfigFlags has neither warning user in a standardized
format functionality nor passing warning callback functions to other upper level
libraries such as client-go.
This commit adds an ability that user can set warningPrinters
according to their IOStreams and this warningPrinters will be used
to raise possible warnings happening not only in cli-runtime but
also in client-go.
* Pass warning callback function in ConfigFlags to shortcutExpander
This commit passes warning callback function to print possible
warnings happened in shortcut expander to warn user in a
standardized format.
* Add integration test for CRDs having ambiguous short names
This commit adds integration test to assure that warning message
related to this ambiguity is printed when resources are being retrieved via their short name
representations in cases where multiple resources have same
short names.
This integration test also ensures that the logic behind which resource
will be selected hasn't been changed which may cause disperancies in
clusters.
* Remove defaultConfigFlag global variable
* Move default config flags initialization into function
* Skip warning for versions of same group/resource
* Run update-vendor
* Warn only once when there are multiple versions registered for ambiguous resource
* Apply gocritic review
* Add multi-resource multi-version ambiguity unit test
The kubelet restarts working pods with an exponential back-off delay,
with a maximum cap of 5 minutes. The waiting 1 minutes may happen to be
in back-off time.

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!).
These wrapper functions set labels in addition to injecting the annotation into
the test text. It then becomes possible to select tests in different ways:
ginkgo -v --focus="should respect internalTrafficPolicy.*\[FeatureGate:ServiceInternalTrafficPolicy\]"
ginkgo -v --label-filter="FeatureGate:ServiceInternalTrafficPolicy"
ginkgo -v --label-filter="Beta"
When a test runs, ginkgo shows it as:
[It] should respect internalTrafficPolicy=Local Pod to Pod [FeatureGate:ServiceInternalTrafficPolicy] [Beta] [FeatureGate:ServiceInternalTrafficPolicy, Beta]
The test name and the labels at the end are in different colors. Embedding the
annotations inside the text is redundant and only done because users of the e2e
suite might expect it. Also, our tooling that consumes test results currently
doesn't know about ginkgo labels.
Environments, features and node features as described by
https://github.com/kubernetes/enhancements/tree/master/keps/sig-testing/3041-node-conformance-and-features
are also supported.
The framework and thus (at the moment) test/e2e do not have any pre-defined
environments and features. Adding those and modifying tests will follow in
a separate commit.
If something goes wrong during the test registration phase, the only solution
so far was to panic. This is not user-friendly and only allows to report one
problem at a time.
If initialization can continue, then a better solution is to record a bug,
continue, and then report all bugs together.
This also works when just listing tests. The new verify-e2e-suites.sh uses that
to check all test suites (identified as "packages that call
framework.AfterReadingAllFlags", with some exceptions) as part of
pull-kubernetes-verify.
Example output for a fake
framework.RecordBug(framework.NewBug("fake bug during SIGDescribe", 0))
in test/e2e/storage/volume_metrics.go:
```
$ hack/verify-e2e-suites.sh
go version go1.21.1 linux/amd64
ERROR: E2E test suite invocation failed for test/e2e.
ERROR: E2E suite initialization was faulty, these errors must be fixed:
ERROR: test/e2e/storage/volume_metrics.go:49: fake bug during SIGDescribe
E2E suite test/e2e_kubeadm passed.
E2E suite test/e2e_node passed.
```
-list-tests is a more concise alternative for `ginkgo --dry-run` with one line
per test. In contrast to `--dry-run`, it really lists all tests. `--dry-run`
without additional parameters uses the default skip expression from the E2E
context, which filters out flaky and feature-gated tests. The output includes
the source code location where each test is defined. It is sorted by test
name (not source code location) because that order is independent of
reorganizing the source code and ordering by location can be achieved with
"sort".
-list-labels has no corresponding feature in Ginkgo.
One possible usage is to figure out what values might make sense for
-focus/skip/label-filter.
Unit tests will follow in a future commit.
Always printing "Enabling in-tree volume drivers" whenever the E2E suite is
initializing doesn't provide any useful information and makes output of the
upcoming -list-tests look weird.
