Process aerosol analysis in grib2 format via UPP in GCAFS

[ypwang19]

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 analysis fields are generated by adding aerosol increments (aeroinc_gaussian) to the atm.f006 background file.

This feature is implemented in atmanlupp job in GCAFS workflow.
