[jira] [Created] (SAMZA-1958) Add an API in ScalarUdf to get the Udf display information

Weiqing Yang created SAMZA-1958:
-----------------------------------

             Summary: Add an API in ScalarUdf to get the Udf display information
                 Key: SAMZA-1958
                 URL: https://issues.apache.org/jira/browse/SAMZA-1958
             Project: Samza
          Issue Type: Sub-task
          Components: sql
            Reporter: Weiqing Yang
             Fix For: 0.15.0


Currently if users implement new UDFs or if Samza SQL implements a new system UDF, they need to manually register that UDF's information in the "listFunctions" of Samza executor. So we may need to require UDFs to provide a function of getting their "SamzaSqlUdfDisplayInfo", then Samza executor can get the UDF information from SamzaSqlApplicationConfig.udfResolver(or SamzaSqlApplicationConfig.udfMetadata) instead of registering UDFs manually.
