Review comment:
I think it's better to use `common.sh#start_taskmanagers` here.

> Add stress deployment end-to-end test
> -------------------------------------
>
> Key: FLINK-10720
> URL: https://issues.apache.org/jira/browse/FLINK-10720
> Project: Flink
> Issue Type: Sub-task
> Components: E2E Tests
> Affects Versions: 1.7.0
> Reporter: Till Rohrmann
> Assignee: Stefan Richter
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.7.0
>
>
> 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).
