Depends on Azure/ARO-HCP#5728

Summary by CodeRabbit

This PR increases the Azure Red Hat OpenShift Hosted Control Plane (ARO-HCP) development e2e testing capacity by expanding the BOSKOS resource pools in the OpenShift CI infrastructure.

Infrastructure Changes:

• Increases aro-hcp-dev-shard1-slot resources from 3 to 6 slots for e2e testing
• Adds a new resource pool aro-hcp-dev-hypershift-westus3-slot with 1 slot for the westus3 region

Files Modified:

• core-services/prow/02_config/_boskos.yaml: Manually extends the BOSKOS quota slice configuration with 3 additional shard1 slots and introduces the new westus3 hypershift slot
• core-services/prow/02_config/generate-boskos.py: Updates the generator script to dynamically create 6 shard1 slots (instead of 3) and adds generation of the new westus3 hypershift slot

These changes scale up the e2e test parallelization capacity for ARO-HCP development, enabling faster CI feedback for the ARO-HCP team. The PR is currently on hold pending upstream coordination with Azure/ARO-HCP repository.

Walkthrough

Adds a new Boskos resource type aro-hcp-dev-hypershift-westus3-slot (1 slot) and expands aro-hcp-dev-shard1-slot from 3 to 6 entries. Changes are made in both the generator script (generate-boskos.py) and the generated output (_boskos.yaml).

Changes

ARO HCP Boskos Slot Expansion

Layer / File(s)	Summary
Generator script: CONFIG entry and slot generation loops core-services/prow/02_config/generate-boskos.py	Adds aro-hcp-dev-hypershift-westus3-slot to the CONFIG map and updates the E2E slot generation block to emit 6 shard1-slot-* names (range(6) instead of range(3)) and 1 hypershift-westus3-slot-* name.
Generated YAML: new slot type and expanded shard1 names core-services/prow/02_config/_boskos.yaml	Inserts a new resource block for aro-hcp-dev-hypershift-westus3-slot-00 and appends shard1-slot-03 through shard1-slot-05 to the existing aro-hcp-dev-shard1-slot entry, both with state: free.

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 contains no Ginkgo test files; only YAML configuration and Python utility script changes related to Boskos resource management.
Test Structure And Quality	✅ Passed	Pull request contains only configuration files and a Python generation script, not Ginkgo test code. Custom check is inapplicable.
Microshift Test Compatibility	✅ Passed	No new Ginkgo e2e tests are added in this PR. The changes only modify BOSKOS configuration files and a Python script that generates resource quotas for CI infrastructure, not e2e test code.
Single Node Openshift (Sno) Test Compatibility	✅ Passed	No new Ginkgo e2e tests added. PR only modifies infrastructure configuration files (_boskos.yaml and generate-boskos.py) for test resource quota allocation, not test code.
Topology-Aware Scheduling Compatibility	✅ Passed	PR changes are test infrastructure resource allocation config (BOSKOS), not deployment manifests or operator code with scheduling constraints. No topology-aware scheduling issues apply.
Ote Binary Stdout Contract	✅ Passed	This PR modifies only BOSKOS configuration files (_boskos.yaml) and a Python generation script, not OTE test binaries. The check is inapplicable to infrastructure configuration changes.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	No new Ginkgo e2e tests are added in this PR. Changes are limited to Boskos configuration files and a Python script for generating resource quotas—not test implementations.
