Add simple physics diagnostics

[peverwhee]

The following outfld calls exist in the simple physics schemes in CAM. Since these came in before history in CAM-SIMA, we're missing the diagnostics and we should add them back in.

QRS: Temperature tendency associated with the relaxation toward the equilibrium temperature profile (equivalent to TTEND)

tj2016
QRS: Temperature tendency associated with the relaxation toward the equilibrium temperature profile
KVH: Vertical diffusion diffusivities (heat/moisture)
KVM: Vertical diffusion diffusivities (momentum)
DTV: T vertical diffusion
DUV: U vertical diffusion (equivalent to UTEND)
DVV: V vertical diffusion (equivalent to VTEND)
VD01: Q tendency (vertical diffusion)

Just an FYI. When I was running FHS94 a few weeks back, I found that the variable QRS in CAM was identical to TTEND in CAM-SIMA. To state the obvious QRS is the only physics tendency in FHS94.

Thanks @adamrher

I took a look and it seems that DUV and DVV are the same as UTEND and VTEND in tj2016.

So, updated list that we need to add:
tj2016
QRS: Temperature tendency associated with the relaxation toward the equilibrium temperature profile
KVH: Vertical diffusion diffusivities (heat/moisture)
KVM: Vertical diffusion diffusivities (momentum)
DTV: T vertical diffusion
VD01: Q tendency (vertical diffusion)

Perhaps those existing tendencies variables should just be renamed TTEND->QRS (in HS94) and UTEND->DUV (in tj2016)...? I only suggest this because TTEND/UTEND/VTEND are not process specific names, and more similar to something like PTTEND, which is the sum of all physics temperature tendencies regardless of what physics suite you're running. PTTEND is calculated in diag_phys_tend_writeout which is a diagnostic called at the end of tphysac in CAM, and I think we are punting on replicating these CAM diagnostics in CAM-SIMA, which would need to be brought as an interstitial routine and declared in the suite definition file.

@adamrher that makes sense. updated the description to (hopefully) reflect what we want to do.
