      * Previously, when installing a cluster on vSphere using the control plane machine set Technology Preview feature, the resulting control plane machine sets had duplicate failure domains in their configuration. With this update, the installation program creates the control plane machine sets with the correct failure domains. (link:https://issues.redhat.com/browse/OCPBUGS-25453[*OCPBUGS-25453*])

      Description of problem:

       CMPS was supported in 4.15 on vsphere platform when enable TechPreviewNoUpgrade. but after I build the cluster with no failure domains/single failure domain setting in install-config. there were three duplicated failure domains.

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

          4.15.0-0.nightly-2023-12-11-033133

      How reproducible:

          install a cluster with TP enabled and don't set failure domain (or set single failure doamin) in install-config.

      Steps to Reproduce:

          1. do not config failure domain in install-config (or set single failure doamin).
    2. install a cluster with TP enabled
    3. check CPMS with command:   
       oc get controlplanemachineset -oyaml

      Actual results:

      duplicated failure domains.
        failureDomains:
     platform: VSphere
     vsphere:
     - name: generated-failure-domain
     - name: generated-failure-domain
     - name: generated-failure-domain
    metadata:
     labels:

      Expected results:

       failure domain should not duplicated when setting single failure domain in install-config.
 failure domain should not exists when not setting failure domain in install-config.
