   Divide the logic into tow procedures.
     1. Removing comparison in BE and FE related to version hash.  #2335 #2358 
     2. Modify API in FE/BE. Removing all version hash.
   
   Procedure 1 is completed in Doris-0.13, procedure 2 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 FE. So we should removing version hash related to 
comparison in FE and BE in Doris-0.13 firstly. And Doris-0.13 upgraded, all 
comparison related to version hash is removed, we can remove version hash in 
all API  in BE and FE.
