      Description of problem

      Version-Release number of selected component (if applicable):

      Nutanix starts to support multi prism-element (PE) failure domains in OCP 4.15. When doing the local testing, found that when multi-PE failure domains are configured, the installer terraform still creates the 3 control-plane nodes in a single PE, not spreading through the 3 PEs configured with the failure domains.

      How reproducible:

       Always

      Steps to Reproduce:

      Use the 4.15 nightly build installer, configure multi-PE failure domains in the install-config.yaml. See the doc on how to configure: https://docs.google.com/document/d/1TA9vCH-3X_GttJ4fHg39sstdhBPCR7S83N1R8rzXFuk/
      
      Run the installer to provision the Nutanix OCP cluster, check where (which PE) the control-plane nodes are running.

      Actual results:

        The control-plane nodes are with the single PE (prism-element).

      Expected results:

       The control-plane nodes are evenly spread through the PEs configured in the failure domains.
