[BUG]: Namespacing Partial Functionality

[Iranaphor]

Description of the bug

The launch file hunter_platform/hunter_pltf_gazebo/launch/launch_sim.launch.py brings up the gazebo sim for the hunter. When this is launched it, by default, has no namespace as expected.

Ideally a namespace is applied through this launch file being included under a GroupAction with an associated PushRosNamespace. However under this approach, only the following topics and nodes are namespaces appropriately when deployed with PushRosNamespace('GROUP'):

Nodes:
/GROUP/robot_state_publisher

Topics:
/GROUP/joint_states
/GROUP/robot_description

Included within the launch_sim.launch.py file is the spawn_entity node. This can take an additional argument of: '-robot_namespace', '/SPAWN', which should (when absent) use the rclpy.get_namespace() by default. When set manually, this will apply a namespace to:

Nodes:
/SPAWN/back_lidar_link_plugin
/SPAWN/front_lidar_link_plugin
/SPAWN/gps_base_controller
/SPAWN/imu1_controller
/SPAWN/gazebo_ros2_control

Topics:
/SPAWN/gps_base_controller/vel
/SPAWN/back_lidar/points
/SPAWN/back_lidar/points_PointCloud2
/SPAWN/front_lidar/points
/SPAWN/front_lidar/points_PointCloud2

Further in this launch file, is the robot_description_content which can apply a prefix to the xacro file. When this is applied as "prefix:='DESC_'",, it will add the prefix to the following items:

Nodes:
/SPAWN/DESC_back_lidar_link_plugin
/SPAWN/DESC_front_lidar_link_plugin
/SPAWN/DESC_gps_base_controller
/SPAWN/DESC_imu1_controller

Topics:
/DESC_gps_base/fix
/SPAWN/DESC_gps_base_controller/vel

With all three applied, the following topics and nodes are still not namespaced:

Nodes:
/back_camera_camera_controller
/front_camera_camera_controller

Topics:
/back_camera/camera_info
/back_camera/depth/camera_info
/back_camera/depth/image_raw
/back_camera/depth/image_raw/compressed
/back_camera/image_raw
/back_camera/image_raw/compressed
/back_camera/points
/front_camera/camera_info
/front_camera/depth/camera_info
/front_camera/depth/image_raw
/front_camera/depth/image_raw/compressed
/front_camera/image_raw
/front_camera/image_raw/compressed
/front_camera/points
/gps_base/yaw

These should all namespace appropriately given the launch file being run with a RosPushNamespace. Each of the files associated with this need to have namespacing compatibility available.
