-When an app calls `fetchWithExpirationDuration:completionHandler`, cached
-parameter values are used unless the last successful fetch occurred more than 12
-hours ago, or unless a value less than 43200 (the number of seconds in 12 hours)
-is specified for `TimeInterval`. If a cached value is not used, updated
-parameter values are fetched from the Remote Config service.
