// old networking plugin, and there won't be old pods "floating around".
// This means whenever we create or update a networking plugin, we should be sure that:
// 1. the selector is role.kubernetes.io/networking=1
// 2. every object in the manifest is labeleled with role.kubernetes.io/networking=1
// TODO: Some way to test/enforce this?
// TODO: Create "empty" configurations for others, so we can delete e.g. the kopeio configuration
// if we switch to kubenet?
// TODO: Create configuration object for cni providers (maybe create it but orphan it)?
