KEDA CloudEventSource API

The CloudEventSource and ClusterCloudEventSource custom resources define HTTP or Azure Event Grid destinations where KEDA delivers CloudEvents when scaling events occur. Events follow the CloudEvents specification v1.0 and carry reason codes and messages for events such as ScalerError, ScaledObjectReady, ScaledObjectDeleted, and AuthenticationFailed. Optional event type filters allow consumers to subscribe to only the events they care about.
