Review Comment:
   I need to add multiple sub types for shuffle type indicating hash functions 
for it (doris use crc32, spark use murmr32, hive v1, v2, hudi-hash all these 
are different).
   and for each if I add a separate shuffle type then `ChildPropertiesRegulator 
. visitPhysicalHashJoin()` will become too bloated. 
   
   @morrySnow Can you please suggest a better way to handle the same?
