Bring external land component support to UFS

[uturuncoglu]

Description of changes

This PR aims to extend nems application to support external land component. Along with these changes, the UFS model will be able to support following RTs:

• datm_cdeps_lnd_gswp3: 1 day run with CDEPS GSWP3 dataset
• datm_cdeps_lnd_gswp3_rst: restart run with CDEPS GSWP3 dataset
• control_p8_atmlnd_sbs: side-by-side test with active atmosphere, uses same configuration with control_p8 and the interaction with FV3 is uni-directional to allow comparing the results coming from FV3/CCPP/NOAHMP with external NOAHMP component

Specific notes

Contributors other than yourself, if any: No
CMEPS Issues Fixed (include github issue #):
A minor issue related with the land component which does not provide cpl_scalars to mediator is fixed.

Are changes expected to change answers? (specify if bfb, different at roundoff, more substantial) No

Any User Interface Changes (namelist or namelist defaults changes)? No

@mvertens @DeniseWorthen i am currently testing with CESM. I'll update you about it.

[uturuncoglu]

all tests are passed without any issue.

[DeniseWorthen]

Sorry for the delay in reviewing. I don't see any issues w/ this PR.

[uturuncoglu]

@DeniseWorthen Thanks. I think we will merge this first and update CMEPS in UFS side later with your UFS level PR. Right?

[DeniseWorthen]

Yes, my original thought was that your UFS PR will need new baselines for the added tests. But if we did just a CMEPS PR, we would be able to get that one out of the way first, since it will be able to be combined w/ another non-baseline change PR. But at this point there isn't much in the queue. So I'm not sure it is worth it to do them separately.

[uturuncoglu]

@DeniseWorthen Then, let's merge this and you just update CMEPS in UFS side. I think it would be easier. @mvertens could you review this PR. Then, we could merge it.

[mvertens]

This PR looks fine. @uturuncoglu - can you please run one fully coupled CESM case to see that everything runs before merging. I will not have time to do that today.

[uturuncoglu]

@mvertens I have already run CESM testlist_drv.xml test with cesm2_3_beta09 and they were okay. If you want me to test again. I could do it.

[mvertens]

@uturuncoglu - thanks! I should have checked. Please go ahead and merge.
