Update external event recorder to be compatible with the upstream k8s EventRecorder interface. Since the EventRecorder interface methods don't return any error, add a logger to the external event recorder to log any errors. Add an event type constant for trace events. Update `controller.Events.EventWithMetaf()` to send the available metadata information to the kubernetes event recorder with `AnnotatedEventf()`. Update the tests to work with the function signature changes. Signed-off-by: Sunny <darkowlzz@protonmail.com>
Since events.Recorder implements the k8s EventRecorder interface, there is no need of the controller.Events any more. The reconcilers can embed the k8s EventRecorder and use a events.Recorder recorder. Update the events.Recorder to embed a k8s event recorder to pass events to k8s along with an external recorder. The trace events are passed to k8s recorder as a normal event since it only accepts normal and warning event types. Update tests to use testenv with suite_test.

Rebased and added object information in the recorder logger.

controller.Events.This change updates the external event recorder to be compatible with the k8s EventRecorder interface and embed the k8s event recorder. Since the
events.Recorderimplements the k8s EventRecorder, it can be directly used in reconcilers that embed the k8s EventRecorder interface. This makes thecontroller.Eventsredundant. The k8s event recorder is embedded in theevents.Recorderto be able to post events to k8s and any external recorders.This also introduces a new event type
EventTypeTraceto map with the severity type trace.Since the kubernetes API only accepts Normal and Warning event types. Sending a Trace event results in:
E1018 10:37:56.133861 1768805 event.go:334] Unsupported event type: 'Trace'In order to keep the trace events only in k8s, the trace events are passed to k8s as Normal events. Trace events are not passed to the external event recorders, refer #139.
Since the
EventRecorderinterface methods don't return any error, the external event recorder has a logger to log any event recording related errors.Replacing
corev1.ObjectReferencewithruntime.Objectdue to the function signature change required updating the existing tests objects to beruntime.Objectcompatible.Closes #134
