Adds FBWINDS support to global-workflow (#2082)

This PR addresses issue #1221. The following was accomplished:

- A new Rocoto job is added; `jobs/rocoto/fbwinds.sh`;
- `workflow/applications/gfs_cycled.py` is updated to include the `fbwinds` task;
- `workflow/applications/gfs_forecast_only.py` is updated to include the `fbwinds` task;
-  A new function is added to `workflow/rocoto/gfs_tasks.py`, `fbwinds` is added as new GFS (only) task;
- `workflow/rocoto/tasks.py` is updated to include the `fbwinds` task.

Resolves #1221
