WIP Hypershift BM - Agent based via Assisted Installer with IP echo server

[asood-rh]

Summary by CodeRabbit

• Adds a scheduled bare-metal HyperShift agent test job for OVN-Kubernetes with Assisted Installer.
• Provisions a Python HTTP IP echo service on the provisioning host and publishes its host IP and URL.
• Adds failure-tolerant cleanup that removes the service, systemd unit, and executable after testing.
• Adds ownership metadata for the new CI step registry components.

Walkthrough

The change adds HyperShift agent OVN ipecho provision and deprovision steps. It also adds a scheduled bare-metal OVN egress-IP debug job that runs provisioning, a wait step, and cleanup.

Changes

HyperShift OVN ipecho debug flow

Layer / File(s)	Summary
Provision the ipecho service ci-operator/step-registry/hypershift/agent/ovn/ipecho/provision/*	Adds a systemd Python HTTP ipecho service, readiness checks, shared output files, step configuration, metadata, and ownership.
Run the scheduled OVN debug job ci-operator/config/openshift/openshift-tests-private/openshift-openshift-tests-private-release-5.0__amd64-nightly.yaml	Adds a twice-monthly bare-metal HyperShift agent OVN egress-IP debug job with assisted provisioning, a wait step, deprovisioning, and a 20-hour timeout.
Deprovision the ipecho service ci-operator/step-registry/hypershift/agent/ovn/ipecho/deprovision/*	Adds cleanup configuration and a script that stops and removes the service and files, reloads systemd, and absorbs cleanup errors.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Pre-merge checks failed

Please resolve all errors before merging. Addressing warnings is optional.

❌ Failed checks (1 error)

Check name	Status	Explanation	Resolution
No-Sensitive-Data-In-Logs	❌ Error	The provision step logs caller source IPs through the HTTP handler/journal and prints the internal bridge IP and URL via curl and echo.	Suppress or mask source and bridge IPs in CI stdout and journal diagnostics; keep unmasked values only in protected step artifacts required by the test.

✅ Passed checks (14 passed)

Check name	Status	Explanation
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title check	✅ Passed	The title clearly describes the new bare-metal HyperShift agent workflow and IP echo server added by the pull request.
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	The PR adds CI YAML, shell scripts, metadata, and OWNERS files; searches found no Ginkgo title constructs or dynamic test names.
Test Structure And Quality	✅ Passed	The PR changes only CI YAML, shell scripts, metadata, and OWNERS files; no Ginkgo test code or It/Eventually/BeforeEach constructs are present to review.
Microshift Test Compatibility	✅ Passed	The PR adds CI configuration and ipecho step scripts only; no new Ginkgo test declarations were found, and the job invokes the existing wait step.
Single Node Openshift (Sno) Test Compatibility	✅ Passed	The PR adds CI YAML, OWNERS, and shell provisioning steps only; it adds or modifies no Ginkgo e2e tests or It/Describe/Context/When bodies.
Topology-Aware Scheduling Compatibility	✅ Passed	PR changes CI job configuration and ipecho shell steps only; the full diff has no deployment/controller code or topology-sensitive scheduling constraints.
Ote Binary Stdout Contract	✅ Passed	The PR changes no Go or OTE suite code. The only print runs in a remote systemd ipecho service, while shell echoes are CI step logs, not openshift-tests JSON stdout.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	The PR adds CI YAML and shell helpers only; it invokes the existing generic wait step and adds no Ginkgo It, Describe, Context, or When test code.
No-Weak-Crypto	✅ Passed	The PR adds an HTTP IP-echo service and CI wiring only; added-line and source searches found no MD5, SHA1, DES, RC4, Blowfish, ECB, custom crypto, or secret comparisons.
