Add a qc_flag of failed microwave cloud function using simulated brightness temperature (Tb) in all-sky DA. Observation should be tossed out when cloud amount cannot be derived from observed Tb or simulated Tb, but current GSI fails in doing that. See the note:
GEOS-ESM/swell#66 (comment)
A failure in cloud function using observed Tb or simulated Tb results in the observation being tossed in JEDI/UFO. Therefore, this PR would make this QC identical in GSI and JEDI though impact in final analysis is likely trivial.
