Extend delv to be able to test RPZ [ISC-support #14736]
Description
A customer has asked for a stand-alone tool that can be used to test policy zone rules - primarily focused on verifying the effects of the introduction of NSIP rules on the resolution of names that may be served by things masquerading as DNS servers.
Request
The ability to specify a zone name, zone file, and response-policy options to delv, have it configure that zone and response-policy on the view used internally for resolution, and then perform the requested queries.
