Added setting of cartesian speed and acceleration (#53)

* added re-use of max_velocity_scaling_factor and max_acceleration_scaling_factor from move_action goal to cartesian_path_request

* Removed getter and setter of 'max_cartesian_speed' to avoid confusion
as the corresponding value of the MotionPlanRequest.msg
(respectively the self.__move_action_goal.request object) is currently
not used in moveit2.
--> The 'max_cartesian_speed' variable requires the
'default_planner_request_adapters/SetMaxCartesianEndEffectorSpeed'
which currently only exists in moveit1.
