IdledAtAnnotation indicates that a given object (endpoints or scalable object)) is currently idled (and the time at which it was idled).

NeedPodsReason is the reason for the event emitted to indicate that endpoints should be unidled.

PreviousScaleAnnotation contains the previous scale of a scalable object (currently only applied by the idler).

UnidleTargetAnnotation contains the references and former scales for the scalable objects associated with the idled endpoints.

CrossGroupObjectReference is a reference to an object in the same namespace in the specified group.

RecordedScaleReference is a CrossGroupObjectReference to a scale subresource that also has the previous replica count recorded.
