    Update sphinxext to include scope_types in docs

    Since we've added ``scope_types`` as an attribute to policy rules, it
    makes sense to include this information in documentation. End users
    will need to know what type of scope is required to pass a specific
    policy rule when services start incorporating system scope and scope
    types.
