Adds vehicle name to ros1 camera frame_ids.

[lukas-utopiacompression]

Makes tf frame_ids of multiple cameras w/ same name distinct.

Fixes #4578

PR #4478 fixes exactly this behavior but for ROS2. This PR fixes it for ROS1

About

Adds the vehicle name to camera related tf frame_ids. This avoids ambiguous frame_ids, if cameras of multiple
vehicles have the same name.

1. Use above settings.json
2. open Blocks environment
3. roslaunch airsim_ros_pkgs airsim_node.launch
4. Open either rviz, or rqt with the rqt_tf_tree plugin

Screenshots (if appropriate):

Before - frames img0_optical and img0_body are ambiguous i.e. some drones don't have a transformation to it:

After - every drone now has their own transformations to their respective camera:
