Handle expiration of mobile map packages

100.5 Runtime added ability to handle expiration of mobile map packages -

>Time-based expiration of mobile map packages and mobile scene packages is now supported in ArcGIS Runtime. An author can choose either a hard expiration where the package is not usable after the expiry date, or a soft expiration where a warning message my be displayed to the user but the package is still usable after the expiry date. Packages with such expiration constraints can be created using an upcoming version of ArcGIS Pro.
