Use Redis Pub/Sub for messaging between BungeeCord and Minecraft servers

[jamezrin]

Basically what the title says. The Spigot Plugin Messaging API is very limited and requires a player to be online in the server that uses the API.

An alternative to Redis could be sockets, but there is more work to do for that to work out ok...

It's generally a good idea, but not every single server has Redis installed or just can't/don't wannt to install it. Therefore the messagint between the proxy and the spigot server is good as it is, but you could do it with Sockets as you already said, even tho this can also lead to issues. But what you can techincally do is by creating an option in the config for this, so people can choose what they want to use.
