The JobManager actor supervises jobs running in a single SparkContext, as well as shared metadata.
It creates a SparkContext (or a StreamingContext etc. depending on the factory class)
It also creates and supervises a JobResultActor and JobStatusActor, although an existing JobResultActor
can be passed in as well.
