@StephanEwen , I fixed the iteration tests to make it stable yesterday, and
I think it may be related with the static incremental id in
`StreamTransformation`, especially for multi tests to be executed in different
sequences. And I took another way to check and verify all the `JobVertex`s from
generated `JobGraph`.
The CI build finished just now and I found there are two failures. The
first one is because of timeout, and the second one is for flink-dist module
and seems unrelated with my pull request.
