Create and publish/subscribe to Kafka topic

[demortes]

The ASP.NET project for API handling will need to subscribe to the same topic that's published to.

• Docker compose should be set up to run Kafka
• Destination host server should run a Kafka container
• MiscTwitchApi should subscribe to the topic "twitch.chat" and "twitch.event". Great test of Observables in C#.
  • If twitch.event = offline, clear session database.
• Twitch bot should report all chats to the Kafka topic twitch.chat and events to Twitch.event
