THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!

- User-defined source parallelism. Source parallelism can be configured via global parallelism, or can be assigned by DataStream, Table/SQL(FLIP-367).
- Connector static parallelism inference (e.g. hive source).
- Dynamic parallelism inference. For batch jobs which use adaptive batch scheduler(FLIP-187), the current implementation will use a global default source parallelism as the inferred parallelism for sources.
