Previously ProbeController was starting probing as soon as SetBitrates() is called. As result these probes would often timeout while connection is being established. Now ProbeController receives notifications about network route changes. This allows to start probing only when transport is connected. This also makes it possible to restart probing whenever transport route changes (will be done in a separate change).
