Separate UPP Driver into Assets and Standalone classes.

[christinaholtNOAA]

AC

• The UPPAssets class has been created and tested.
• The schema for the assets and standalone drivers are separated. Assets schema is re-used in the standalone driver.
• The appropriate portion of the schema is validated, depending on the driver.

Description

UPP can either run in a standalone mode for each forecast lead time or inline with the execution of the ufs-weather-model. The two different methods of running UPP should be captured as part of the supported UW Drivers.

That means the Asset driver will handle the creation of the namelist, copying and linking files. In contrast, the standalone UPP driver class will instantiate an Assets driver object for preparing assets, create a run script, and provide a means of executing the UPP program.
