This PR shows an example of the new self-transitioning functionality implemented in required PRs ros2/rcl_interfaces#97, ros2/rcl#618, and ros2/rclcpp#1064. Ideally, I think the lifecycle_service_client should react to the lifecycle_talker having an error rather than just knowing it will happen as that would be more true to a real world example, but for a demo and proof of concept, maybe it's better to keep it simpler.
