model: scikit: Add new scikit based models

[pdxjohnny]

@sakshamarora1 is working on adding more models to scikit models

Current issue is that any classes with __init__ arguments that don’t have default values are not being added as properties to cls.CONFIG.

Plan

• Focus on figuring out what models have no parameters that have no default values.
• Verify that those models work
• Identify a few models which are failing
• Get the make_config implemented (Replace args and config methods with CONFIG property #164)
• Change namedtuple(...) calls which create dffml_config into calls to make_config(...)
  • This requires parsing the docstring to identify which types a scikit parameter should be (this can be done at any time)

MAPPING = {
    "string": str,
    "list of dicts": List[dict],
    # ...
}

• Make sure we have all the mapping for at least one class so we can start testing this out.

In the future we will make it so we can dynamically instantiate any scikit model.

This issue is a part of #29
