Review Comment:
   Please note that flink ```sql-client.sh -f``` is only supported after 
version 1.13. And ```sql-client.sh``` at version 1.13 and 1.14. and 1.15 have 
some completely incompatible contents in these three versions.  If we add flink 
sql support. We should put it in the frontend page and document to let users 
distinguish it.
