auto scale up and down with many named backends in k8s

[aapjeisbaas]

I created a cron job to scale down empty servers.
There is room for improvement but it runs stable and that's the most important thing I guess.

This YAML is an example and is not intended to be directly applied.
It consists of 3 parts

1. the mc-router with service account and service
2. the shutdown cronjob with service account
3. the actual minecraft server with service and storage

Part 3 is the only part you need to replicate for the number of servers you want.
