------------------------------------

             Summary: Add blink built-in functions from FlinkSqlOperatorTable to BuiltInFunctionDefinitions
                 Key: FLINK-15609
                 URL: https://issues.apache.org/jira/browse/FLINK-15609
             Project: Flink
          Issue Type: Sub-task
          Components: Table SQL / API
            Reporter: Jingsong Lee
             Fix For: 1.10.0


In FLINK-15595, CoreModule should contains all functions in FlinkSqlOperatorTable. Otherwise, resolution Order is chaotic. I think it is time to align blink built-in functions to BuiltInFunctionDefinitions.

Impact to legacy planner: user can not use the function name directly that he define function with the same name of blink built-in function in catalog. I think it is reasonable, since he will migrate his job to blink planner.

What do you think? [~twalthr] [~dwysakowicz]
