[aerogear-dev] Push message encryption to support PushMessageData of Push API

Hi all, As we discussed previously, Firefox already supports sending push message data to browser if it will be encrypted. Since version 50, Google Chrome also support it [1]. But it requires for UPS to store "public key" and "auth secret" for each Installation [2]. See current example of sending push notifications with a payload[3]. Storing of two additional fields is not a big deal. But we also have to refactor PushNotificationSender [4], because it consumes a collection of device tokens as a param instead of a collection of installations. Any thoughts about how we can implement it with minimal changes?
