Goal

• Allow users to set different Root volume types for each Control plane machine as a day-2 operation through CPMS
• Allow users to set different Root volume types for each Control plane machine as install-time configuration through install-config

Why is this important?

• In some OpenStack clouds, volume types are used to target separate OpenStack failure domains. With this feature, users can spread each Control plane root volume on separate OpenStack failure domains using the ControlPlaneMachineSet

Acceptance Criteria

• Once the CPMS is updated with different root volume types in the Failure domains, CCPMSO spins new master machines with their root volumes spread.

Dependencies (internal and external)

1. OpenShift-on-OpenStack integration with CPMS (OSASINFRA-3100)

Previous Work (Optional):

1. 4.13 FailureDomains tech preview (OSASINFRA-2998)
