      * When the `confidentialCompute` parameter is set to `Enabled`, the `OnHostMaintenance` parameter must be set to `Terminate`.
      Previously, there was no validation of the values of these parameters, and misconfiguration resulted in a misleading error message `Confidential Instance Config is only supported for compatible cpu platforms`.
      With this release, these parameters are validated.

      Description of problem:

          Specifying N2D machine types for compute and controlPlane machines, with "confidentialCompute: Enabled", "create cluster" got the error "Confidential Instance Config is only supported for compatible cpu platforms" [1], while the real cause is missing the settings "onHostMaintenance: Terminate". That being said, the 4.16 error is mis-leading, suggest to be consistent with 4.15 [2] / 4/14 [3] error messages. 

FYI Confidential VM is supported on N2D machine types (see https://cloud.google.com/confidential-computing/confidential-vm/docs/supported-configurations#machine-type-cpu-zone).

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

      4.16.0-0.nightly-2024-05-21-221942    

      How reproducible:

      Always

      Steps to Reproduce:

          1. Please refer to [1]

      Actual results:

          The error message is like "Confidential Instance Config is only supported for compatible cpu platforms", which is mis-leading.

      Expected results:

          4.15 [2] / 4/14 [3] error messages, which look better.

      Additional info:

          FYI it is about QE test case OCP-60212 scenario b.
