JarScheduler

Different processors of the stream application can use different jars. JarScheduler is the scheduler for different jars.

For a DAG of multiple processors, each processor can have its own jar. Tasks of same jar is scheduled by TaskScheduler, and TaskSchedulers are scheduled by JarScheduler.

In runtime, the implementation is delegated to actor JarSchedulerImpl
