CLI tools for basic CWL package definition

[fmigneault]

In order to help a new app package developer with all the required information in the creation of an new process, a CLI could be made. It should have following features :

• create template:
  generates a basic WPS App with CWL exec-unit and minimal "FILL ME" fields
  • optional input arguments that can plug the repetitive arguments into the proper "FILL ME" locations
  • some validation of the provided values? eg validate docker ref is found?
  • ignore flag for disable validation?
• process validation:
  provide a reference to an existing process description (file/href), and return errors as applicable
  (this should be straight-forward as most of it is already done, just need to map args to functions to make CLI)
• ... ?

Use one of the many examples instead: https://github.com/crim-ca/weaver/tree/master/tests/functional/application-packages
Not worth the effort considering low gains from this feature.
