Convert rk_stratiform_tend (CAM4) to CCPP

[jimmielin]

Conversion of rk_stratiform_tend (Rasch and Kristjansson prognostic cloud microphysics and CAM4 macrophysics) from CAM4 to CCPP.

Preparation work

• Convert cldwat (will be called prognostic_cloud_water) to CCPP (full conversion)
• Partial conversion of cldfrc (will be called cloud_fraction) to CCPP (partial conversion, will be CCPP compliant, but will serve as internal dependency of rk_stratiform_cloud_fractions_run)
• Convert pkg_cld_sediment (will be called cloud_sedimentation) to CCPP (unknown whether will be full conversion)
• Move pkg_cldoptics to to_be_ccppized for utility routines for cldefr (effective radii), cldems (emissivity), cldovrlap (cloud overlap), cldclw (cloud liquid water path); at the very least, de-chunkize these routines

Conversion of rk_stratiform_tend to CCPP:

• Phase 1: rk_stratiform_sedimentation
• Phase 2: rk_stratiform_detrain_convective_condensate
• Phase 3: rk_stratiform_cloud_fractions (calls internal dependency cloud_fraction_run)
• Phase 4: rk_stratiform_microphysics (stratiform cloud macrophysics and microphysics)
• (call prognostic_cloud_water_run here)
• (compute and apply tendencies - rk_stratiform_prognostic_cloud_water_tendencies)
• Phase 5: rk_stratiform_microphysics_tendencies (calls internal dependency cloud_fraction_run again and applies microphysical tendencies)
• Phase 6: rk_stratiform_cloud_optical_properties save cloud water and ice particle sizes for radiation (calls cldefr to-be-ccppized)
• Finalize suite_rasch_kristjansson.xml

Diagnostics

• Create SIMA diagnostics for rk_stratiform_diagnostics
