Deploy a fresh set of Azure cloud clusters for CCLM testing:

• 1 hub cluster (ACM + MCE)
• 2 managed clusters with CNV + MTV

Key requirements:

• Non-overlapping CIDRs between managed clusters (see parent story for values)
• Worker instance type: Standard_D8s_v3 (8 CPU, 32GB) or larger
• Use openshift-install IPI with custom install-config.yaml to set CIDRs at install time
• Preserve the metadata.json output for each cluster (needed by subctl cloud prepare azure – see MachineSet template)

CIDR allocation:

(Per Submariner Azure Quickstart and CCLM Network Guide)

Why fresh deployment:
The existing Azure env (investigated Feb 2026) has identical CIDRs on both spokes and D2s_v3 workers – both are set at install time and cannot be changed post-deployment.
