> 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.
