Thibault Saunier 98e5c5e862 ges: Implement a new GESDiscovererManager object
Allowing better control over the way discovery happens and allowing
us to expose a proper API.

This also adds the potential of implementing more multi-threaded
discovery in a clean way in the future.

This allows us to cleanly expose the new
GstDiscoverer::load-serialize-info signal.
