Review comment:
wondering if we can somehow add to the logic of
`isFitForMetadataBasePlan` checker for distinct count. basically one additional
check to see if it is dictionary encoded?
we already did additional check for COUNT anyway. good to add DISTINCTCOUNT
too?

Review comment:
why change the query to be tested? not the explained plan node below?
