Enhance validate command to perform Metaschema and constraint-based validation of modules

[aj-stein-gsa]

User Story

As a developer of Metaschema-based software, in order to find precise modeling errors XML Schema based validations cannot find, I would like the metaschema-cli validate ... to natively used the Metaschema model and constraint-based validation of models.

NOTE: This request came from a consideration during a review of a code cleanup in #230 (comment).

Goals

• More precise error detection for Metaschmea models
• More precise, informative error reporting upon detection that is more helpful than XML Schema validation

Dependencies

@aj-stein-gsa Would you provide more details around how you would like this to work? How do you see the command changing as far as arguments? What behavioral change should be implemented?

Sure thing. I may have said it in an overly complex way, but what I mean is that this command would take any Metaschema module and validate it against the Metaschema constraints for the modules themselves to report any constraint violations, not just XML schema validation. That is currently not done, correct? I know you did some refactoring but I could not find that in the code last I checked.
