    Query the RBAC rules.

Parameter:

Keyword Parameters/Class attributes:

    source          The name of the source role/attribute to match.
    source_indirect If true, members of an attribute will be
                    matched rather than the attribute itself.
    source_regex    If true, regular expression matching will
                    be used on the source role/attribute.
                    Obeys the source_indirect option.
    target          The name of the target role/attribute to match.

    tclass_regex    If true, use a regular expression for
                    matching the rule's object class.
    default         The name of the default role to match.
    default_regex   If true, regular expression matching will
