    [TRAFODION-1634] Update stats on Hive tables is slow
    
    Fix suggested by Feng Qiang (Vito). Update stats for Hive table uses
    INSERT to populate the sample table. It has now been changed to use
    UPSERT USING LOAD.
    There is also some cleanup change to remove code related to dp2sampling
    and the adjustment it required when table had varchar columns.
