Cleanup of symlinks for wxflow, etc., use of DATAoutput for model, update to triggers for wavepost jobs, and other misc. stuff

[aerorahul]

Description

This PR collects a few things. Specifically it:

• removes softlinks to wxflow and relies on the setting of PYTHONPATH if wxflow is not available as an importable module. This will streamline when wxflow is part of a virtualenv or loaded via spack-stack
• moves the links of soca and ufsda into ush/python which is added to PYTHONPATH. This applies consistency for all importable python modules
• uses DATAoutput for writing model output into. In particular, it creates and writes to FV3ATM_OUTPUT, MOM6_OUTPUT, CICE_OUTPUT and WW3_OUTPUT. In addition, WW3 restarts are written to WW3_RESTART
• uses log.points and log.wave_grid files for triggering wave post-processing jobs instead of binary output from the next forecast output time.

This portion of the code changed file formats from how the model is writing it out to the more readable YYYYMMDD.HH0000.restart.ww3.nc file name structure. I think we might need additional changes if this is removed, but maybe I'm not thinking through everything?

Do you have output of the extended S2SW test on WCOSS2 and/or the low res gfs cycled test so I can take a look at the output/logs or do I need to run these tests?

[aerorahul]

I am running tests on Gaea C6. The logs for low res gfs cycled test will drop into /gpfs/f6/drsa-precip3/world-shared/Rahul.Mahajan/RUNTESTS/COMROOT/C96C48mx500_S2SW_cyc_gfs_tlc. Feel free to look around and let me know if you find something out of place. I too, will keep an eye.

I removed this portion of the code because the model is now configured to write the WW3 restarts directly into DATArestart/WW3_RESTART instead of in DATA and then linking the restart file from DATA into DATArestart/WW3_RESTART

It is possible that the model in segment 2 (or RERUN=YES) needs to know what the right restart filename for WW3 is. As soon as my tests conclude, I will know that and will make a fix if one is needed.

https://github.com/NOAA-EMC/global-workflow/blob/develop/ush/forecast_det.sh#L101-L106 uses the more readable (my preferred) naming convention of the WW3 restart files.

This also uses the more readable format of restarts: https://github.com/NOAA-EMC/global-workflow/blob/develop/ush/forecast_postdet.sh#L501-L530

The code section above these lines also wouldn't work depending on if it's a re-run or you are copying to COM.

Looks good but needs more descriptive title

That was just a little joke from the DA team

Looks good. I like the consolidation of those wavepost job definitions. Thanks @aerorahul !
