Title: Groupjoinfinder find fks

Update the GroupJoinFinder to find Foreign Keys that may be part of a join. This marks the child table TableSource as containing a valid foreign key join to the parent table.

Currently the optimizer doesn't do anything with this information, it just flags the TableSource.
