Description

This PR resolves issue ##4233

This PR adds the capability to process analysis tracer fields into aerosol AOD product in GRIB2 format using the upp tool within the GCAFS workflow. The input for UPP is aerosol analysis on Gaussian grid. Aerosol variables in atmospheric analysis file (analysis.atm.a006.nc) are all missing data, such that the aerosol Gaussian tracer analysis fields are generated by adding aerosol increments (aeroinc_gaussian) to the atm.f006 background file.

This feature is implemented in analcalc, atmanlupp, and atmanlprod jobs in GCAFS workflow.
This PR depends on parm/product/gcafs* files, such that it will work after #4147 merged.

Resolves #4233

Do we need anything else or is this ready for test and final review?

Since this is only used for the GCAFS system probably best to put this into an if statement and only call for that system.
