add the capabilty to dynamically generate GSI satinfo, convinfo ozinfo files for reanalysis

[jswhit2]

What new functionality do you need?

Currently config.anal has an if/then/else loop that sets env vars SATINFO, OZINFO, CONVINFO that contain paths to different gsi info files for different periods over the last several years. For reanalysis, we need a solution that works back to 1979. Rather than add to the if/then/else block in config.anal, I have created a set of scripts that generate *info files dynamically given a date (https://github.com/NOAA-PSL/build_gsinfo). What is needed is a way to use those scripts in global-workflow. Note this is only needed for GSI - for JEDI the needed functionality is included in observation_chronicle (https://github.com/NOAA-EMC/jcb-gdas/tree/develop/observation_chronicle/atmosphere).

What are the requirements for the new functionality?

the global-workflow can dynamically generate and use GSI satinfo, ozinfo and radinfo files based on the analysis date.

Acceptance Criteria

• the workflow dynamically generates the correct satinfo/ozinfo/convinfo files when using GSI and uses them

Suggest a solution (optional)

Create a new RUN_ENVIR ('reanl') and have the build_gsinfo scripts generate satinfo, ozinfo and convinfo files based on ${PDY}${cyc}
