Search before asking

• I had searched in the issues and found no similar feature requirement.

Description

after #10989 finishes, all functions in PythonGateway just look like https://github.com/apache/dolphinscheduler/blob/7196b125d9a6612f2f175c2190d7758a09d7e0b9/dolphinscheduler-api/src/main/java/org/apache/dolphinscheduler/api/python/PythonGateway.java#L394-L396 and maybe we can find some way not declaire the function in PythonGateway, and directly import this function from python api side, we currently have some simple code in https://github.com/apache/dolphinscheduler/blob/5289b09817396046489b28857ad54a85c5ffddb2/dolphinscheduler-python/pydolphinscheduler/tests/integration/test_java_gateway.py#L40-L53

and maybe we can do some things like that, and maybe at last our PythonGateway will only have https://github.com/apache/dolphinscheduler/blob/7196b125d9a6612f2f175c2190d7758a09d7e0b9/dolphinscheduler-api/src/main/java/org/apache/dolphinscheduler/api/python/PythonGateway.java#L566-L594 content
