Address magic numbers for Autonomous Paths

[Koltara]

We have several magic numbers present in our autonomous paths (inside PathFollower.java). Let's convert these magic number's into actual named data points.
Ex. (0, 0, 0 degrees) -> (kCenterGoalLineX, kCenterGoalLineY, kCenterGoalLineStartAngle)

Please create a feature branch off of develop, and commit changes there. When work is finished, create the pull request to merge the changes into develop. Do NOT complete the pull request.
