Fixes #46, #50

This change is in reaction to the following PR: ros-controls/ros2_control#1659 where a timeout is added for the switch controller service. This timeout is hardcoded as 5 seconds here: https://github.com/ros-controls/ros2_control/blob/8779757f7e5cdb5e6998d9b162e65015003e3c1f/controller_manager/controller_manager/spawner.py#L332

Further discussion should be had on proposing to parameterize that timeout so that we can adapt for low resource sims which are slow to launch and/or making the timeout based on ROS time.

@hilary-luo Can you keep this the default behaviour but add a launch argument allowing the sim to be launched paused?

@roni-kreinin I can do that, is there an expected use case for this? As things currently stand, if they do not press play within 5 seconds of launch then the simulation will fail.

Its just to maintain backwards compatibility with how it worked before.
