add hercules to load_ufsda_modules.sh

[RussTreadon-NOAA]

What new functionality do you need?

UFS-DA (GDASApp) jobs load modules via ush/load_ufsda_modules.sh. At present this script only supports Hera and Orion. GDASApp can now run on Hercules. This issue is opened to load JEDI modules when running GDASApp jobs on Hercules.

What are the requirements for the new functionality?

Load JEDI modules when running GDASApp jobs on Hercules.

Acceptance Criteria

Able to run UFS-DA jobs on Hercules with the correct modules loaded.

Suggest a solution (optional)

Add logic to the Orion section of ush/load_ufsda_modules.sh to support Hercules as has already been done in ush/load_fv3gfs_modules.sh

Work for this issue will be done in RussTreadon-NOAA:feature/ufsda_modules

Updated ush/load_ufsda_modules.sh tested on Hercules. The proper modules are loaded and GDASApp executables run to completion. Also test on Hera and Orion. GDASApp executables still run to completion as previously was the case. Lines in ush/load_ufsda_modules. related to prod_util are not needed.
