    I've already added a version check between `JobClient` and `JobManager`. Will there be any further review of this?

> Problem: there can be subtle errors when actors from different Flink versions communicate with each other, for example when an old client (e.g. Flink 0.9) communicates with a new JobManager (e.g. Flink 0.10-SNAPSHOT).
> We can check that the versions match on first communication between the actors and fail if they don't match.
