Splittable DoFn: Gives the runner access to RestrictionTracker
Changes the SplittableParDo transform so that ProcessFn uses a
runner-supplied hook to run the @ProcessElement method, giving
it, among other things, the RestrictionTracker, so the runner
can initiate checkpointing/splitting with it at will.
Introduces a default implementation of said hook, which limits
the number of outputs and duration of the call. This implementation
is used in tests and in Direct runner. Dataflow Streaming runner
will also use this implementation, while Dataflow Batch runner
will be more sophisticated.
