updates from RTs for wave restart name and nml files

[DeniseWorthen]

Description

Two PRs have been merged and the corresponding changes need to be made in the workflow.

1. update CMEPS to allow bilinear ATM<->WAV mapping for global coupled application; utilize custom restart names for WW3 (was #1684)  ufs-community/ufs-weather-model#1692. This changes the name of the WW3 restart file and fixes For a "continue" run, WW3 should not start unless a restart is present ufs-community/ufs-weather-model#1590.

This change required in the nems.configure file is to add user_sets_restname = true in the WAV_attributes:: section. The restart file will then be consistent with the restart names produced by ICE and CMEPS. It will also contain an application specific name, eg. ufs.hafs.ww3.r.YYYY-MM-DD-SSSSS or ufs.cpld.ww3.r.YYYY-MM-DD-SSSSS

2. add cmeps capable atm-wav test ufs-community/ufs-weather-model#1407. This added use of nml files for the wave model. The template for the file are ww3_shel.nml.IN. Also, the list of point output is now in a separate file ww3_points.list. Both are located in the UFS tests/parm directory. The structure of the nml that needs to be parsed is

&input_nml
  input%forcing%winds      = 'C'
  input%forcing%currents   = '@[WAV_CUR]'
  input%forcing%ice_conc   = '@[WAV_ICE]'
  input%forcing%ice_param1 = '@[WAV_IC1]'
  input%forcing%ice_param5 = '@[WAV_IC5]'
/

&output_type_nml
  type%field%list = '@[OUTPARS_WAV]'
  type%point%file = 'ww3_points.list'
/

&output_date_nml
  date%field%outffile  = '1'
  date%field%stride    = '@[DTFLD]'
  date%point%outffile  = '1'
  date%point%stride    = '@[DTPNT]'
  date%restart2%stride = '@[DT_2_RST]'
/

The variables are consistent w/ the variables in the current inp file with the exception of the forcing fields. These are now either C for coupled or F for not. The values for WAV_ICE1 and WAV_ICE5 should be F unless WW3-CICE6 coupling is used (currently not implemented in UFS).

For the HAFS application, the use of outfile=1 will now create time-stamped files, for example 20190829.060000.out_grd.ww3 in place of out_grd.ww3.
