URL: https://github.com/apache/flink/pull/8439
 
 
   ## What is the purpose of the change
   
   After FLINK-12407 Python Table API will align with current Java Table API. So, In the following Table API development, it's better to add a new user interface to the Java Table API will also need to be added to the Python Table API. So In this Jira, we want to add the test_completeness to check the user interface of Python Table API aligns with Java Table API. 
   
   I'm not sure if we want to force contributors to contribute to the Python Table API while developing the Java Table API. But at least we should have the ability to automatically check if Python is aligned with Java functionality.
   
   ## Brief change log
     -  Add `PythonAPICompletenessTestCase` which is base class for Python API completeness tests.
     - Add `TableAPICompletenessTests` which test whether the Python `Table` is consistent with Java `org.apache.flink.table.api.Table`.
     - Add `EnvironmentAPICompletenessTests` which test whether the Python `TableEnvironment` is consistent with Java `org.apache.flink.table.api.TableEnvironment`.
