    Description

      Issue description: Once the admission control is configured (with the MAX_MEM_ESTIMATE_FOR_ADMISSION, MEM_LIMIT, etc,etc query options), if a user bypass the default setting setting the query options in the session it can cause queries failures in the pools configured (e.g decreasing MAX_MEM_ESTIMATE_FOR_ADMISSION and increasing MEM_LIMIT).

      Improvement: It will be great to have a further checkboxes (with those default values) like "do not allow user to override this value".
      The value can be changed eventually by the query optimizer, but we do not allow users to change MAX_MEM_ESTIMATE_FOR_ADMISSION at all.
