camerabin: remove photography interface implementation from camerabin

Browse source 
Remove notify signal proxy for video-source. Application can use
video-source directly from now on to get notified of property changes.
Add monitoring scene-mode property change to select lowest possible
framerate for video capture when night mode is selected.

Fixes #616923

* GstCameraBin implements #GstPhotography interface, which can be used to set
* and get different settings related to digital imaging. Since currently many
* of these settings require low-level support the photography interface support
* is dependent on video src element. In practice photography interface settings
* cannot be used successfully until in PAUSED state when the video src has
* opened the video device. However it is possible to configure photography
* settings in NULL state and camerabin will try applying them later.
