Update motor controller configuration

CAN SparkMax Controllers

Implementation Plan

Either add or update existing motor objects to create a differential drivetrain with 2 left motors and 2 right motors, where one motor is in follow mode. The motor controllers are CAN based SparkMax and the motors are Rev Neo.

Affected Subsystem(s):

• Drivetrain

Details: REV SparkMax API: https://codedocs.revrobotics.com/java/com/revrobotics/cansparkbase See DifferentialDrive API docs for information on how to combine the motors into a drive with available tankDrive and arcadeDrive methods.
