In dnsdist local address and port are not exposed in Lua

[jstrika]

In dnsdist --version : 0.0.g5a3409c , configuration file has support for Lua functions but "local" address and port are not accessible.

In example blockFilter(remote, qname, qtype, dh) from https://github.com/PowerDNS/pdns/blob/master/pdns/dnsdistconf.lua we can access "remote" address and port using remote:tostring(), remote:tostringWithPort(), remote:getPort() but not the "local" address and port.

Since dnsdist was recently introduced and not yet widely implemented, did you consider keeping consistency with new pdns v4 and pass "dq" native object instead of strings like: blockFilter(dq) ? That way the community can benefit from "portable" sample code between 2 products and use someting like: dq.remoteaddr:toStringWithPort().." to "..dq.localaddr:getPort()

With the merge of #3233, dnsdist now uses a DNSQuestion dq, as close as possible as the PDNS4 one. The "local" address and port are available in this new object. Thank you for the suggestion!

Fantastic, thank you!
