Merge "Introduce WifiRoamScansPreferenceController"

        controllers.add(new WifiDisplayCertificationPreferenceController(context));

        // enable wi-fi verbose logging

        // aggressive wifi to mobile handover

        // always allow wifi roam scans

        controllers.add(new WifiRoamScansPreferenceController(context));

        // mobile always active

        // tethering hardware acceleration

        // select usb configuration
