Virtual Kubelet is the multi-tenant Virtual Kubelet infrastructure of Koupleless. It has been refactored from the open-source Virtual Kubelet to support managing multiple Virtual Kubelets in a single process.

This is achieved through the implementation of the Tunnel interface, which allows custom resources to be disguised as K8S Nodes.
