Downgrade FMS to 2019.01.03

[DusanJovic-NOAA]

Description

Downgrade FMS to 2019.01.03.
Small changes in cmake build system due to FMS version change.
Improve error handling in rt.sh when ecflow is used. Scripts cleanup and refactoring.

Issue(s) addressed

In order to merge (unify) ufs-weather-model and ufs-s2s-model changing the FMS to the exact version used by s2s is required.

Testing

Regression test will be performed on all Tier-1 platforms.
New baseline (develop-20200805) has been created, because of file format change in FMS (CDF2 to HDF5). All restart files and all history files (created using write component) are bit-identical.

Dependencies

The code changes look good to me. I noticed that the atmos_4xdaily files are still there, so I assume we will have another commit to clean up that.

Looks good to me - I'll try this code on cheyenne while we are waiting for hera to come back.

I tested killing jobs on Cheyenne and it seems to work:

• kill -15 on the rt.sh job kills all jobs in the queue
• hitting Ctrl + C from the rt.sh job itself doesn't kill the queued jobs (is this intended?)

[climbfuji]

To complete the testing, I ran the rt_gnu.conf tests on Cheyenne against the old/existing baseline. All tests ran to completion within the walltime used usually for cheyenne.gnu but "failed" as expected, due to differences in atmos_4xdaily*.nc. All good to go!

Looks good to me.
