[static] Solid::DeviceNotifier *DeviceNotifier::instance()

Returns a pointer to the global DeviceNotifier instance to allow for its use with QObject::connect();

 auto notifier = Solid::DeviceNotifier::instance();

 auto refresh = [this] (const QString &udi) {
     Solid::Device device(udi);
     if (device.is<Solid::StorageDrive>()) {
         qInfo() << "A new storage drive was added!";
