      Description of problem:

      The current RAN RDS reference files include a fixed list of workloadHints values for the Performance Profile [1]

  workloadHints:
    realTime: true
    highPowerConsumption: false
    perPodPowerManagement: false

This is setting a specific configuration, although we have traditionally considered other options as valid, such as:

- Setting "highPowerConsumption: true / perPodPowerManagement: false" to force C0 C-state
- Or setting "highPowerConsumption: false / perPodPowerManagement: true" to enable per-pod power management.

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

      Seen on RAN RDS versions 4.14 through 4.18

      How reproducible:

      Always

      Steps to Reproduce:

          1. Run oc cluster-compare with the RAN RDS as reference against a Performance Profile YAML with different workloadHints values

      Actual results:

          Deviations found

      Expected results:

          No deviations found
