High CPU usage

[sfxworks]

With barely any connections, spikes pretty high. Currently deployed as-is with the example servers replaced with my own. Happens with bungee, paper only, and vanilla with the service annotation. I don't see any major hits to the kube-api server, so it doesn't look like it's taxing that thankfully.

There is nothing abnormal in the logs of the mc-router pod.

Applied a CPU quota to mitigate this

Aaaah ya know, I just saw the tag that I was using from the example. I'll change it to your latest and close it if I don't notice it again.

All is well!

I'll open up a PR later to update that.
