create tool function for validating types

[sbillinge]

could look something like this hacky code:

            bad_milestone_types = [ms for ms in milestones if ms.get('status')
                                   not in PROJECTUM_STATI]
            bad_milestone_types_output = [f"{ms.get('name')}, {ms.get('uuid')}, "
                                          f"{ms.get('status')}" for ms in
                                          bad_milestone_types]
            if bad_milestone_types:
                print(f"WARNING: some milestones in {projectum.get('_id')} have "
                      f"bad status types: ["
                      f"{bad_milestone_types_output}]")

but in tolls and with tests and can be called to validate whatever in whatever
