provide a setCameraInfoService

[lgeo3]

For now the camera info are stored directly in the cpp files (camera_info_definitions).
It could be really useful to provide a service like setCameraInfo as cameraInfoManager do (http://wiki.ros.org/camera_info_manager)

Do you think it's a good idea ?

If yes, @nlyubova can you write the code ?
