> The aim of this new features is to expose a client to the user which allows to cancel
a running job, retrieve accumulators for a running job, or perform other actions in the future.
Let's call it {{JobClient}} for now (although this clashes with the existing JobClient class
which could be renamed to JobClientActorUtils instead).
> The new client should be returned from the {{ClusterClient}} class upon job submission.
The client should also be instantiatable by the users to retrieve the JobClient with a JobID.
> We should expose the new JobClient to the Java and Scala APIs using a new method on the
{{ExecutionEnvironment}} / {{StreamExecutionEnvironment}} called {{executeWithControl()}}
(perhaps we can find a better name).
