Description

Hi,

I'm trying to set up the driver for a stereo camera, so I need two CameraInfoManager instances.
The hope was that I could set up the classes in such a way that they advertise:

/stereo/node_name/left/set_camera_info and 
/stereo/node_name/right/set_camera_info

However, they always seem to end up advertising the exact same service name...?

/stereo/node_name/set_camera_info

Is there a workaround?

I saw that on the rolling branch, there is a "namespace" (ns) parameter that one can pass to the CameraInfoManager constructor, however it's missing on the jazzy branch. Is there a workaround? Or could this be backported?

Research direction

Compare the rolling-branch CameraInfoManager constructor and its namespace parameter with the Jazzy implementation. Reproduce the stereo setup with two CameraInfoManager instances and verify whether the left and right set_camera_info services receive distinct names. Done means the requested namespace behavior is available on Jazzy or a documented workaround is established.
