ML_MODEL_UNLOAD unloads a model
        from MySQL HeatWave AutoML.
      
        As of MySQL 9.0.0,
        ML_MODEL_UNLOAD does not check
        whether the model specified is in the model catalog. If it is
        not, ML_MODEL_UNLOAD will
        succeed, but will not unload any model. Use
        ML_MODEL_ACTIVE to check which
        models are active and owned by the user.
