Design

To group notifications each polling window, this implementation follows Producer-Consumer pattern

Producer: watch gateway event and register notification queue

1. Watch GuildEmojiUpdate sent from Gateway Event
2. Triggers pushEmojiToQueue() to push notifyRequest

Consumer: send a notification on new emojis to a pre-defined channel

1. Get the notifyRequest pushed by the producer
2. Register the notifyRequest to a notifyQueue
3. (every N minutes) Get requests from the notifyQueue and send a message to the channel
