Make configuration parameters for rrt util

[HussainGynai]

The constants in question are:

robocup-software/soccer/src/soccer/planning/primitives/rrt_util.cpp

Lines 18 to 24 in 38b370a

	ConfigBool* RRTConfig::enable_rrt_debug_drawing;
	ConfigDouble* RRTConfig::step_size;
	ConfigDouble* RRTConfig::goal_bias;
	ConfigDouble* RRTConfig::waypoint_bias;
	ConfigInt* RRTConfig::min_iterations;
	ConfigInt* RRTConfig::max_iterations;

We want them to be declared using the new ROS parameters interface. An example of using the parameters interface:
https://github.com/RoboJackets/robocup-software/blob/ros2/soccer/include/rj_vision_filter/params.hpp
https://github.com/RoboJackets/robocup-software/blob/ros2/soccer/src/rj_vision_filter/params.cpp

For the following parameter declaration:

DECLARE_NS_INT64(kVisionFilterParamModule, filter::health, init)

You can access it using filter::health::PARAM_min.
