Description:

Code for gfs, cfsr, and gefs datm datamodes is very similar (just with different function names). This PR removes the duplicates. As gefs datm datamode is already in ESCOMP/CDEPS, gefs is retained here. Note that GFS, GEFS, CFSR, etc. input datasets are still handled via streams in the same way, just with datamode == 'GEFS'. Sunset gfs_hafs datamode no longer used.

These PRs have also been merged for commit queue (via PR to this branch on their behalf):

• Add ability to read increment files on native cubed sphere grid #2304
• Improve error checking in rt.sh #2388

Commit Message:

* UFSWM -  Unify CDEPS gfs, cfsr, and gefs datm datamodes. Add ability to read increment files on native cubed sphere grid.  Update rt scripts to fix checking the job exit status from Slurm and PBS schedulers.
