Fix warlock model creation

Commands like glance md-namespace-show <namespace> fail because
of a breaking change in warlock 1.3.0's model creation factory
method.

Warlock introduced a new kwarg 'resolver' in model_factory method
but changed its position with the 'base_class' kwarg. Since we
were calling the model_factory method with positional arg, this
broke the model creation.

Closes-Bug: #1596573
