> Add config to enable HoS DPP only for map-joins

>
> HoS DPP will split a given operator tree in two under the following
> conditions: it has detected that the query can benefit from DPP, and the
> filter is not a map-join (see SplitOpTreeForDPP).
> This can hurt performance if the the non-partitioned side of the join
> involves a complex operator tree - e.g. the query {{select count(*) from
> srcpart where srcpart.ds in (select max(srcpart.ds) from srcpart union all
> select min(srcpart.ds) from srcpart)}} will require running the subquery
> twice, once in each Spark job.
> Queries with map-joins don't get split into two operator trees and thus don't
> suffer from this drawback. Thus, it would be nice to have a config key that
> just enables DPP on HoS for map-joins.
