Could you check whether the {{flink-high-parallelism-iterations-test}} fulfills this ticket?

> In order to test Flink's scalability, I suggest to add an end-to-end test which tests the deployment of a job which is very demanding. The job should have large {{TaskDeploymentDescriptors}} (e.g. a job using union state or having a high degree of parallelism). That way we can test that the serialization overhead of the TDDs does not affect the health of the cluster (e.g. heartbeats are not affected because the serialization does not happen in the main thread).
