Hi all . In this feature we need update the database schema. Because it is not yet sure which version of this feature will go online, so I will temporarily put the table schema change sql in the incubator-dolphinscheduler/sql/upgrade/1.4.0_schema/mysql/dolphinscheduler_ddl.sql file, after determining the version number later Then modify the version number
