Update job submissions on WCOSS2

[EdwardSafford-NOAA]

Update job submissions on WCOSS2 to conform to latest NCO guidance. Items to be addressed include:

• eliminate -V option in all submissions. If environmental variables are needed they should be specified individually using -v.
• all small serial jobs should use -l place=shared,select=1:ncpus=1:mem=100MB to use shared nodes.
• no job scripts should use a -l option on the shebang line. Only the cron script may use that option (on the first line only) in this form: SHELL=/bin/bash -l. I don't think this is an issue but it should be inspected and confirmed.
