GFSv16.3.9 - temporary satingest changes for NOAA-21

[KateFriedman-NOAA]

Description
Email from @ADCollard

I need to update GFS at that time to turn off NOAA-21 ingest as the CRTM is still causing issues (and August 29 is when the satingest upgrade will start the NOAA-21 data flow).
I think I have been given the green light from Steven Earle to turn on NOAA-20 OMPS and PlanetIQ on August 29.

Production update sliding in before planned v16.3.8 (now v16.3.9). Some changes already made in PR #1804. Additional updates needed to resolve build issue with tropcy (issue #1812). See NOAA-EMC/GSI#611
