Virtual Queue Server

[mitch0s]

Instead of requiring us to host a separate server as the queue server, an option can be elected to have the bungeecord instance act as the queue server, with players put into the void etc like they normally would.

Just updated my PistomQueue, which is almost what you're asking for here, except it is still a standalone queue server, but takes very few resources to run. Since the queue server is pretty much just a place that the proxy places players before yoinking them out to send to the real server, it doesn't actually have to do very much at all.

I think something like LimboAPI would be good for this.
