Add CNO test extension binary

[anuragthehatter]

Summary

• Register the cluster-network-operator OTE binary in openshift-tests so it can discover and run CNO-specific e2e tests from the payload.

Based on openshift/cluster-network-operator#3015

Test plan

• Verify openshift-tests discovers the CNO extension binary
• Verify CNO e2e tests are listed and runnable

🤖 Generated with Claude Code

Summary by CodeRabbit

• Tests
  • Extended test infrastructure to support additional binary extraction from cluster-network-operator release payloads, improving test coverage capabilities.

Walkthrough

This PR extends the external test binary registry in the test extensions module by adding a new mapping for the cluster-network-operator image, enabling extraction and processing of its test extension binary from the release payload.

Changes

Extension Binary Registry Update

Layer / File(s)	Summary
cluster-network-operator test binary registration pkg/test/extensions/binary.go	Added a TestBinary entry for cluster-network-operator that maps to the test extension binary path /usr/bin/cluster-network-operator-tests-ext.gz in the extensionBinaries registry.

Check name	Status	Explanation
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title check	✅ Passed	The title 'Add CNO test extension binary' directly and concisely describes the main change: registering a new external test binary mapping for the cluster-network-operator image.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
Linked Issues check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Out of Scope Changes check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Stable And Deterministic Test Names	✅ Passed	PR adds a static test binary registry entry with no Ginkgo test definitions. The change contains no dynamic test names or test code that could violate stability requirements.
Test Structure And Quality	✅ Passed	The PR modifies test infrastructure configuration (a binary mapping registry), not Ginkgo test code. The custom check reviews test code quality patterns, which is not applicable here.
Microshift Test Compatibility	✅ Passed	PR only registers external test binary; no Ginkgo e2e tests defined in this file, test code is external and loaded at runtime.
Single Node Openshift (Sno) Test Compatibility	✅ Passed	PR adds binary mapping for CNO test extraction, not Ginkgo test code. Custom check requires "new Ginkgo e2e tests" (It/Describe/Context/When), which are not present in this PR.
Topology-Aware Scheduling Compatibility	✅ Passed	Test binary mapping addition to test framework infrastructure. No deployment manifests, operators, controllers, or scheduling constraints—topology-aware check not applicable.
Ote Binary Stdout Contract	✅ Passed	PR adds only a data structure declaration (TestBinary entry) with no init() functions, stdout writes, or process-level code that could corrupt OTE JSON output.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	PR adds a configuration entry to registry mapping image tag to test binary path. No Ginkgo test code is added in this file.
