SLING-7083 - The StopMojo should block until the process is finished

* allowed the mojo to uniformly block until the instances it tries to stop
are either stopped through the control listener or through sending the
terminate signal
* enforced Java 8, since its java.util.concurrent.Process implementation
provides built-in feature for blocking until a process is terminated
