Implement AuthMeBungee autologin (#1402)

* Implement AuthMeBungee autologin

There is a failing test due to cyclic dependency injection, @ljacqu could you take a quick look at this?

* Try to fix recursive dependency injection

* Fix codestyle

* Fix the subchannel name, again...

* Split BungeeService into BungeeSender and BungeeReceiver
