Kubernetes OS Server - Kubernetes Extension API server exposing OS configuration like sysctl via Kubernetes API

KOSS is a Extension API Server which exposes OS properties and functionality using Kubernetes API, so it can be accessed using e.g. kubectl. At the moment this is highly experimental and only managing sysctl is supported. To make things actually usable, you must run KOSS binary as root on the machine you will be managing.
