Add example server usage

[UnfamousThomas]

To make it clearer how this is designed to be used, a simple server implementation might be useful.

This would include:

1. A server implementation, likely for Minecraft. This would be a simple java application that is easily runnable.
2. Autoscaling implementation for game, to see what that would look like.
3. To facilitate auto scaling, some basic metric collection. Probably, for this, easiest to just do HTTP request that responds with some server metrics.
