Major fixes to enable EASY coupled model experiments

[sanAkel]

The intent of this PR is to make our life simple(r) in setting up GEOS coupled model experiments for all of these resolution combinations.

Proposed changes:

1. The default ocean model for gcm_setup is MOM6. ✅ @sanAkel
2. Use the BCs shared path on discover: /discover/nobackup/projects/gmao/bcs_shared/make_bcs_inputs/ocean/MOM6/ to pick up files needed by MOM6 ✅ @sanAkel
3. To do ❎ @mathomp4 Layout needs to be made consistent.
4. To do ❎ @mathomp4 Options needed to be locked up with the atmosphere as in this table.

Details of what needs to be done.

Layout:

AGCM.rc NX x NY should match MOM’s LAYOUT listed in MOM_override see this table or ⬇️ .

AGCM NX x NY and OGCM NX x NY need to be fixed in AGCM.rc in the following manner:

Configuration Name	AGCM (NX x NY)	OGCM (NX x NY)	Layout in MOM_override
Low	1 x 6	3 x 2	3 x 2
Medium	5 x 36	90 x 2	90 x 2
High	30 x 36	36 x 30	36 x 30

Options:

See following example for setting up high resolution experiment:

discover13.sakella 1046> gcm_setup

Enter the Experiment ID:

Enter a 1-line Experiment Description:

Enter the Atmospheric Model Vertical Resolution: LM (Default: 72)

Enter Choice for Atmospheric Model Microphysics: (Default: BACM_1M)
   BACM_1M  --  3-phase 1-moment Bacmeister et al
   GFDL_1M  --  6-phase 1-moment Geophysical Fluid Dynamics Laboratory
   MGB2_2M  --  5 or 6-phase 2-moment Morrison & Gettleman

Use Hydrostatic Atmosphere? (Default: TRUE)

Do you wish to IOSERVER? (Default: YES or TRUE)

Enter the Processor Type you wish to run on:
   mil  (Milan) (default)
 

Do you wish to run the COUPLED Ocean/Sea-Ice Model? (Default: NO or FALSE)
YES

Choose an Ocean Model: (Default: MOM6)
   MOM5
   MOM6
   MIT

Choose a Seaice Model: (Default: CICE4)
   CICE4
   CICE6

Enter the Ocean Lat/Lon Horizontal Resolution: IM JM (Default: 360 210)
1440 1080
Enter the Ocean Model Vertical Resolution: LM (Default: 50)
75
Enter the choice of  Land Surface Boundary Conditions using: 1 (Icarus), 2 (Default: Icarus-NLv3)
...
...

The user does not need to answer: Enter the Ocean Lat/Lon Horizontal Resolution: IM JM (Default: 360 210): 1440 1080 and Enter the Ocean Model Vertical Resolution: LM (Default: 50): 75. Since a choice was made to run:

• With C180 atmospheric resolution
• And Coupled.

This table provides only one option for ⬆️ choices, hence that should be automatically populated. It can simply echo that it has been filled in.

Similarly for C90 and C12.

⬆️ Items 3 and 4 will be addressed via #542 (review)

[sanAkel]

We need this PR to be merged as well for all the High configuration to be set up automatically.

I've merged in #542 into here. Something is missing and I'm not sure what. But maybe I didn't branch right...

@mathomp4 Is it something I can help with?

CI failed to run in my branch. Not sure why. So I merged mine over here to see if maybe I was missing something. If that fails, I'll get on to the cloud instance and see what I see...

Ah. I see why. This PR is broken on every system but NCCS. I'll need to work on this. One moment.

[mathomp4]

Okay. One more push...

[mathomp4]

Yay! 🎉

[sanAkel]

Fantastic! :)

Works for me as discussed herein
