// RawExtension is used to hold extensions in external versions.

// To use this, make a field which has RawExtension as its type in your external, versioned

// // Internal package:

// 		MyPlugin runtime.Object `json:"myPlugin"`

### Config Translation

With a few exceptions, Istio controllers typically are split in two phases: construction and running.

Construction should create informers (via `kclient.New`), setup a queue (via `controllers.NewQueue`), and register event handlers on the informers.
Often, these handlers are adding something to the queue like `client.AddEventHandler(controllers.ObjectHandler(queue.AddObject))`.
