Change subject: IMPALA-4252: Min-max runtime filters for Kudu
......................................................................


Patch Set 7:

TPCDS is a better workload for min/max filtering than TPCH, because TPCDS relies on dynamic
partition pruning to reduce scan size from the probe side of the joins. 

On the other hand min/max filtering won't help TPCH much because each partition from l_shipdate
and o_orderdate will have the min and max values for l_orderkey and o_orderkey.
