> Add optimization rule to remove gby from right side of left semi-join

> Group by (on same keys as semi join) as right side of Left semi join is
> unnecessary and could be removed. We see this pattern in subqueries with
> explicit distinct keyword e.g.
> {code:sql}
> explain select * from src b where b.key in (select distinct key from src a
> where a.value = b.value)
> {code}
