MCO-1968: Move cloud disruptive test variants to standard jobTier in sippy

[djoshy]

This sets all of MCO's non metal disruptive jobs to the standard tier, permitting them report to MCO's CR. All 4.19/4.20 jobs and metal jobs have been excluded.

Summary by CodeRabbit

• Chores
  • Refined job tier classifications for Machine Config Operator-related tests with granular control by specific platform variants and software releases.
  • Updated default handling for MCO-related jobs to improve resource allocation.
  • Expanded test configuration entries for specific platform types and upgrade paths in CI infrastructure.

Pipeline controller notification
This repository is configured to use the pipeline controller. Second-stage tests will be triggered either automatically or after lgtm label is added, depending on the repository configuration. The pipeline controller will automatically detect which contexts are required and will utilize /test Prow commands to trigger the second stage.

For optional jobs, comment /test ? to see a list of all defined jobs. Review these jobs and use /test <job> to manually trigger optional jobs most likely to be impacted by the proposed changes.

Walkthrough

This PR refactors machine configuration operator (MCO) job tier assignments in the variant registry. It replaces a historical MCO-related candidate entry with granular metal-specific and release-specific MCO variants, introduces new AWS OVN OCL standard entries, and adjusts default MCO job tier handling from candidate to standard.

Changes

Cohort / File(s)	Summary
MCO Job Tier Refactoring pkg/variantregistry/ocp.go	Replaces single {-mco-disruptive} candidate mapping with: three metal-specific MCO disruptive entries (candidate tier), two AWS OVN OCL entries (standard tier), two release-specific MCO entries for 4.19/4.20 (candidate tier), and updates default MCO disruptive handling to standard tier.
JobTier Value Updates pkg/variantregistry/snapshot.yaml	Updates JobTier field from candidate to standard across multiple periodic CI entries. Bulk configuration change with no structural alterations.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~15 minutes

• Verify MCO job tier logic changes produce expected categorization across all variants
• Confirm snapshot.yaml updates align with ocp.go registry changes and reflect intended CI job prioritization
• Ensure no existing functionality is inadvertently affected by the tier reassignments

Pre-merge checks and finishing touches

❌ Failed checks (1 warning)

Check name	Status	Explanation	Resolution
Single Responsibility And Clear Naming	⚠️ Warning	OCPRegistry struct contains duplicate sync.RWMutex fields (mu and lock), violating Single Responsibility by maintaining multiple redundant synchronization primitives instead of one clear locking mechanism.	Remove duplicate lock fields and keep only one descriptive RWMutex (e.g., ruleMutex) to ensure single synchronization responsibility and consistent usage across all methods.

✅ Passed checks (6 passed)

Check name	Status	Explanation
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
Go Error Handling	✅ Passed	PR contains YAML configuration updates without substantive Go error handling code changes, so no violations to assess.
Sql Injection Prevention	✅ Passed	Pull request modifies configuration files with job tier mappings and CI/CD variant registry data. No SQL query construction, database operations, or dynamic query building is present.
Excessive Css In React Should Use Styles	✅ Passed	PR modifies Go and YAML backend files, not React components with inline CSS.
Title check	✅ Passed	The title clearly references the specific Jira issue (MCO-1968) and accurately summarizes the main change: moving cloud disruptive test variants to standard jobTier in sippy.
