> Add Helper methods to move things through lifecycles. init->start is common,
> stop-if-service!=null another. Some static methods can execute these, and
> even call stop() if init() raises an exception. These could go into a class
> ServiceOps in the same package. These can be used by those services that wrap
> other services, and help manage more robust shutdowns.
