// GenerationChangedPredicate implements a default update predicate function on Generation change.
//
// This predicate will skip update events that have no change in the object's metadata.generation field.
// The metadata.generation field of an object is incremented by the API server when writes are made to the spec field of an object.
// This allows a controller to ignore update events where the spec is unchanged, and only the metadata and/or status fields are changed.
//
// For CustomResource objects the Generation is only incremented when the status subresource is enabled.
//
// Caveats:
//
// * The assumption that the Generation is incremented only on writing to the spec does not hold for all APIs.
// E.g For Deployment objects the Generation is also incremented on writes to the metadata.annotations field.
// For object types other than CustomResources be sure to verify which fields will trigger a Generation increment when they are written to.
//
// * With this predicate, any update events with writes only to the status field will not be reconciled.
// So in the event that the status block is overwritten or wiped by someone else the controller will not self-correct to restore the correct status.
