utilize custom restart names for WW3

[DeniseWorthen]

Description

Utilizes configuration variable user_sets_restname in nems.configure to trigger a custom restart file name in WW3. Restarts will be produced with name ufs.APP.ww3.r.YYYY-MM-DD-SSSSS where APP is either cpld or hafs.

If a file of the expected name is not present at restart, WW3 will abort with error

 EXTCDE MSG=required initial/restart file ufs.cpld.ww3.r.2021-03-22-64800 does not exist

On a restart run, the following will be written to stdout

WW3: reading initial/restart file ufs.cpld.ww3.r.2021-03-22-64800

Input data additions/changes

• No changes are expected to input data.
• There will be new input data.
• Input data will be updated.

Anticipated changes to regression tests:

• No changes are expected to any regression test.
• Changes are expected to the following tests:

The hafs_regional_atm_ocn_wav and hafs_regional_atm_wav will fail because the name of the restart file changes. Manual comparison against the existing baseline file shows they are B4B. All other tests pass.

During testing, the hera.intel log was not produced but the rt_ logs were catted manually. The cpld_control_p8 test timed-out for GNU.

@DeniseWorthen It's the goal from the WW3 side for the restart names to be controlled by a WW3 input file instead of a "nems.configure" restart file. Just wanted to make you aware that is a planned change from the WW3 side in the near future.

It is good to know the goal on WW3 side. I think we can get this change in at this time. We can review it when the ww3 restart filename changes are ready. the purpose here is to have consistent restart file names as much as possible for all the model components. Thanks.
