Review commit-by-commit. Don't be scared of the size, the majority is the new vendor dependency.

This PR introduces a link between CLI and/or unit test failures to the underlying CODEOWNERS for the corresponding test files, and pretty-prints a message after the test failure to indicate who can assist with understanding the test and stabilizing the results. See the lines with the ⛑️:

CLI Example:

Unit test example:

Related: cilium/cilium-cli#2936 will allow this logic to also pick up owners from the github workflow where the CLI is run.

Tested here: #37593 (comment) .

Note that for CLI test failures, tests that properly use a.Fail(), a.Fatal() and similar functions to trigger a failure in an individual test action correctly, the attribution will go correctly to the test owner. Tests that fail directly with the top-level test fail functions (ie not t.Fail(), t.Fatal(), ...) will be attributed to @cilium/ci-structure.

Hit #36375 in integration tests, and it's nicely demonstrating the new functionality:

⛑️ The following owners are responsible for reliability of the failing test(s):

Just working on getting github workflows to pass into CLI runs so that we can ensure workflow owners are also mentioned in the list (in case that makes a difference for some multi-owner tests).

@joestringer I think we also want the .github/ changes in stable branches, once the CLI version bump has fully rolled out? Adding backport labels accordingly.

@julianwiedmann julianwiedmann added backport/author The backport will be carried out by the author of the PR. needs-backport/1.15 needs-backport/1.17 This PR / issue needs backporting to the v1.17 branch labels Feb 28, 2025

Operating on older branches will require a little more thought, unless we want this to just point towards Committers for every failure. Let me think on it 👍

This should do the trick, plus backports:

#### 🧑‍💻 Development Experience

- **🧪 Test attribution**: Identify owners of test in GitHub workflow
results to make it easier to connect with other developers on tricky
problems

unix socket is deprecated. The other mechanisms to configure policy via
Kubernetes resources or the local filesystem are preferred

configuration of extra settings on a per-GatewayClass level:
LoadBalancerSourceRangesPolicy, ParametersRef fields. This allows Cilium
to reconcile multiple GatewayClasses with different configurations

unix socket is deprecated. The other mechanisms to configure policy via
Kubernetes resources or the local filesystem are preferred
