// 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.
