Incorporate RASS DA into JEDI for RRFS

[delippi]

Description

The UFO in JEDI is the component that not only computes model-simulated observations, but also houses filters and methods for observation QC, ob errors, and bias correction. The GSI observer is the equivalent. Many forward operators for various observations have been developed for the UFO. These operators can be utilized in RDAS. However these operators still must be tested for RDAS. The steps for transition by observation platform are as follows:

1. Establish IODA processing
2. Establish operator in UFO
3. Establish YAML input file
4. Validate with test assimilation experiments
5. Create ctest, if necessary
6. rass data is bufr obtype=126

Requirements

To create yaml configurations for assimilating RASS data.

Acceptance Criteria (Definition of Done)

• Phase 1 validation (hofx validation using GSI-IODA and GSI-geovals as necessary; GSI vs FV3-JEDI)

• Phase 2 validation (QC validation; no reliance on GSI except to be used as the baseline; GSI vs FV3-JEDI)

• Phase 3 validation (FV3-JEDI and GSI vs MPAS-JEDI)

Phase 1 update:
Phase 1 results are in. These results were created using GSI-IODA, but allowing JEDI to handle the rest (geovals, QC, and oberror inflation). This results also used ObsErrorFactorConventional (OEFC) which had been previously noted to have some issues for other ob platforms, but seems to be working fine here.
