Now that the routecheck subsystem is continuously collecting reachability reports in the background, we can add a hook to LocalBackend for fetching its report. That allows suggestExitNodeUsingTrafficSteering to consult that report when disqualifying candidates, instead of blocking on an immediate probe. Exit node suggestions will only consult the report when the `client-side-reachability` and `client-side-reachability-routecheck` node attributes are both set on the current node.
