Merged the atms_n20 yaml file into RDASApp.

This PR is going to merge the ATMS NOAA_20 JEDI yaml file into RDASApp validated yaml file templates.
As the test in issue #203, atms_n20 data has been tested in MPAS_JEDI including all QC filters and bias correction. Not only the ioda data converted from regular feed bufr data has been tested, but also the ioda data converted from combined regular feed, DBNet, and ESRs bufr data has been tested too.
In addition, this atms_n20 yaml file has included the online domain check filters as described in and issue #224, and removed the 'circle domain check' filter

The Ens3Dvar ctests has passed with this yaml file added on top of the existing yaml file templates.

Thanks @xyzemc, I have the same comments for this yaml as I do for #237.
