cam: Move printing of camera information to CameraSession class

Browse source 
The three CamApp functions listControls(), listProperties() and
infoConfiguration() operate on a camera. They would thus be better
placed in the CameraSession class. Move them there. As they now have no
error to return anymore, make them void functions.
