   Divide the logic into three procedures.
     1. Removing comparison in FE related to version hash.  #2335 
     2. Modify API in FE. Removing all version hash.
     3. Removing version hash in BE.
   Procedure 1, 2 is completed in Doris-0.13, procedure 3 is completed in Doris-0.14.
   
   Why removing version hash involve two Doris release?
   The normal upgrade procedure for Doris is upgrading BE before upgrading FE.
   If version hash in BE have been removed, upgrading BE will lose version hash info which is useful for FF. So we should removing version hash in FE firstly. And after all FE have been upgraded, we can remove version hash in BE and upgrade BE process.
