changed the behavior of driver process termination. Whereas before `Process.destroyForcibly`
was never called, now it is called (on Java VM's supporting that API) if the driver process
does not die within 10 seconds.
> This prevents apps which take longer than 10 seconds to shutdown gracefully from shutting
down gracefully. For example, streaming apps with a large batch duration (say, 30 seconds+)
can take minutes to shutdown.
