User Story:
As an OpenShift Engineer I need to enhance the OpenShift installer to support creating a cluster with additional disks added to control plane and compute nodes so that I can use the new data disks for various OS needs.

Description: 
This task is to enhance the installer to allow configuring data disks in the install-config.yaml.  This will also require setting the necessary fields in machineset and machine definitions.  The important one being for CAPV to do the initial creation of disks for the configured masters.

Acceptance Criteria:
   - install-config.yaml supports configuring data disks in all machinepools.
   - CAPV has been updated with new multi disk support.
   - CAPV machines are created that result in control plane nodes with data disks.
   - MachineSet definitions for compute nodes are created correctly with data disk values from compute pool.
   - CPMS definition for masters has the data disks configured correctly.

Notes:
We need to be sure that after installing a cluster, the cluster remains stable and has all correct configurations.
