PodAutoscaler is a Knative abstraction that encapsulates the interface by which Knative components instantiate autoscalers. This definition is an abstraction that may be backed by multiple definitions. For more information, see the Knative Pluggability presentation: https://docs.google.com/presentation/d/10KWynvAJYuOEWy69VBa6bHJVCqIsz1TNdEKosNvcpPY/edit

type PodAutoscalerSpec 

type PodAutoscalerSpec struct {
	// DeprecatedGeneration was used prior in Kubernetes versions <1.11
	// when metadata.generation was not being incremented by the api server
	//
	// This property will be dropped in future Knative releases and should
	// not be used - use metadata.generation
