refactor(autoware_multi_object_tracker): add configurable tracker parameters

[jakor97]

Description

Extracted autoware_multi_object_tracker parameters from source code, refactored parameters declaration and enabled setting confident_count_threshold for each classification label separately.

Changes

• Extracted tracker-specific parameters: tracker_lifetime, min_known_object_removal_iou, min_unknown_object_removal_iou, distance_threshold, and confident_count_threshold to the multi_object_tracker_node.param.yaml configuration file.
• Introduced TrackerProcessorConfig struct to encapsulate tracker-related parameters and refactored the TrackerProcessor class to use this struct for initialization.
• Updated the TrackerProcessor methods to use the new configuration struct, including createNewTracker, removeOldTracker, removeOverlappedTracker, and isConfidentTracker.

ROS Parameter Changes

Extracted parameters from source code and renamed them according to their use:

Old	New
max_elapsed_time_	tracker_lifetime
min_iou_	min_known_object_removal_iou
min_iou_for_unknown_object_	min_unknown_object_removal_iou
distance_threshold_	distance_threshold
confident_count_threshold_	confident_count_threshold for each label type

Additions and removals

Change type	Parameter Name	Type	Default Value	Description
Added	tracker_lifetime	float	1.0	How long will tracker last
Added	min_known_object_removal_iou	float	0.1	Minimal IoU between associated objects with known label to remove younger tracker
Added	min_unknown_object_removal_iou	float	0.001	Minimal IoU between associated objects with unknown label to remove unknown tracker
Added	distance_threshold	float	5.0	Distance threshold for removing overlapped trackers
Added	confident_count_threshold	std::map<std::string, LabelType>	Label : 3	Number of measurements to consider tracker as confident. Separated for each label.

Effects on system behavior
