Add new features to generate_workflows.sh

[DavidHuber-NOAA]

What new functionality do you need?

The generate_workflows.sh script would benefit through the incorporation of some of the more recent features added to the workflow.

What are the requirements for the new functionality?

• Add a placeholder for GCAFS tests
  • Include build options for GCAFS
• Give a clearer message why generate_workflows.sh exits if the user opts not to delete DATAROOT
• Add an option to use build_compute.sh instead of build_all.sh
• Make the -A (account) option required
• (optional) Convert the getopts section to a getopt to allow long arguments (e.g. --build_compute to use build_compute.sh
• (optional) Add a capability to monitor experiments after they have launched and notify if one or more fail (most useful for Gaea)
• (optional) Add an option to skip running link_workflow.sh

Acceptance Criteria

• All new required features are enabled
• Ideally, long options are incorporated
• Attempting to call generate_workflows.sh without -A raises an error
• All tests run successfully when launched via generate_workflows.sh
