go back to what I originally had: i.e. send h2o shutdown to each node always. However in the multi-machine case, don't do cloud status check in between. Also I had a time delay between the shutdown requests before. get rid of that. Still have the process check for single/multi jvm on local achines, and pkill if still alive. But shouldn't need that unless h2o hung. Prints message if it sees that it needs to do that but doesn't fail the test. Multi-machine doesn't have a pkill mechanism. It has the h2o shutdown and then closes the ssh channel. The os effectively makes that a pkill
