    Add UnionModel support to filter query generator

    The _apply_filters_to_query method did not handle UnionModels
    so objects leveraging it (i.e. RBAC policies) did not have
    queries applied to them.

    This patch corrects it by iterating through the component models
    of the UnionModel and applying the filters to each component model.
    It also adds an API test on RBAC that exercises the filtering.
