This commit include a failing test
TestBaseSubClass.test_attr_class_post_validate
It fails with the error:
Traceback (most recent call last):

AnsibleParserError: the field 'test_attr_class_post_validate' has an invalid value (<class 'units.playbook.test_base.ExampleSubClass'>), and could not be converted to an class. Error was: test_attr_class_post_validate is not a valid <class 'units.playbook.test_base.ExampleSubClass'> (got a <class 'ansible.playbook.base.BaseMeta'> instead)
* wip, test refactoring
* wip, trying to add a parent->child
* wip, fix isa=class.
the ds the base using needs an instance of the class
(ie, whats normally created by the yaml loaders)
* wip, theres no need to argue, I just dont understand parents
* stub a _preprocess_data for coverage
* cleanup, required, parent, etc
