// Event is a report of an event somewhere in the cluster. It generally denotes
// some state change in the system. Events have a limited retention time and
// triggers and messages may evolve with time. Event consumers should not rely
// on the timing of an event with a given Reason reflecting a consistent
// underlying trigger, or the continued existence of events with that Reason.
// Events should be treated as informative, best-effort, supplemental data.
