Updates for integrating RADMON into ADAS

[gmao-msienkie]

I just wanted to mention that, rather than processing the Pyradmon gsidiag_bin2txt a month (or partial month) at a time, I think it would be more convenient to have people create the diag.txt files when running each job segment. There have been hooks for this for quite a while in the DAS scripts for running the gsidiag_bin2txt and there are listings in the silo.arc to copy the text files from $FVWORK.
To activate this, you would just need to add one line to the FVDAS_Run_Config with the command to run gsidiag_bin2txt

setenv GSI_DIAG2TXT "gsidiag_bin2txt.x -passivebc -npred 12" (or something like that with the appropriate options)

Joe, I cannot fold this into develop - ie approve the PR - since echorc.pl is missing. I imagine you placed it in GMAO_Shared/GMAO_etc ... but I don't see it in a PR under GMAO_Shared - you'll need to do that before this can be approved or else the DAS will break.

I haven't tested myself, but it looks fine - and I trust your testing.
