Remove front_steering from steering library
Browse files Browse the repository at this point in the history 
To Accommodate controllers that are not only steering at front or rear
this change remove the `front_steering` variable from
steering_controller_library, as a byproduct of that the notion of
front or rear wheel radius is also removed from dependant controllers
and the library has know "traction_joints_names" and
"steering_joints_names" instead of "front_wheels_names" and
"rear_wheels_names".
