      Description

      It's possible to execute queries with joins and inserts with mt_dop with some small modifications to the Impala code (without the separate join build work). This isn't production-ready because of the other subtasks of IMPALA-3902 but it would be useful to have an experimental flag for people to play around with to test the functionality.
