[CTR1] Port Carrot Controller from lane_detection to drive_ros_trajectory_tracking_control

[xXBasti]

• Create a new class carrot controller based and embed it into the current package structure.

• Create a new branch in the line detection/generator based on:
  https://github.com/tum-phoenix/drive_ros_trajectory_generator/blob/master/src/trajectory_line_creator.cpp

• Remove the carrot controller from our new branchand move it to the our new class.

• Test if the behavior is remains unchanged with a rosbag/Dummy Controller.

Why close it and move it back to in progress? :D
