Just question, do we really need arc::ArcNotificationData. Could
arc::NotificationData be simpler?

I use "Arc" because "ArcBridgeService" has "Arc".

+ public:
+  ArcNotificationData();
+  ~ArcNotificationData();
+
+  std::string key;
+  ArcNotificationType type;
+  std::string message;
+  std::string title;
+  std::string icon_mimetype;
+  std::vector<uint8_t> icon_data;
+  int priority;
+  base::Time timestamp;
+  int progress_current;
+  int progress_max;
+};
+
+}  // namespace arc

+#endif  // COMPONENTS_ARC_COMMON_ARC_NOTIFICATION_DATA_H_
