Summary

• Add new cpms_test stage role that runs the upstream cluster-control-plane-machine-set-operator e2e tests (presubmit + periodic) with branch fallback logic for newer OCP versions
• Add cpms_replace_attrs day2ops procedure ported from the openshift-ir-plugin, which validates CPMS reconciliation by patching failure domains, networks, and security groups on control plane nodes
• Wire the new stage into ocp_testing.yaml and enable it in osp_verification and 4.17_ovnkubernetes_ipi job definitions

Details

The CPMS operator manages the lifecycle of OCP control plane machines. This PR ports the existing Jenkins/IR-based CPMS testing into shiftstack-qa's Ansible automation framework.
New cpms_test stage role:

• Clones the upstream operator repo at the correct release branch (with fallback to main for versions without a release branch)
• Runs make e2e-presubmit and make e2e-periodic with OPENSHIFT_CI=true for JUnit output
• Post-processes results (XML tag modification, HTML conversion) and copies to the report directory for Polarion/ReportPortal
  New cpms_replace_attrs day2ops procedure:
• Creates a test network, subnet, and security group in OpenStack
• Patches the CPMS to inject these resources and swap failure domain attributes between masters
• Waits for full CPMS reconciliation (rolling all 3 control plane nodes)
• Validates that the resulting VMs reflect the expected AZ, volume type, network, and SG changes
• Restores the original CPMS configuration and cleans up test resources
