The Flink Streamlet integration tests doesn't work.

[totosnose]

The Flink Streamlet general tests which works on cloudflow 2.0.18 doesn't work on cloudflow-contrib 2.2.2 (with plugin ver 0.1.1). It seems like stream is empty.

Please try again for version 0.2.0, all unit tests are green, integration tests in cloudflow-it directory are green. (if you run the cloudflow-it tests please make sure you use make prepare-clis to get the right version of flink (cli).
