Add RPZ policy name

[dmgeurts]

PowerDNS-recursor will parse the policy if a request was matched (and likely subsequently blocked or altered).

Logging these policy maps is important when tracking which DNS clients made requests to blocked domains, and there are other uses of RPZ feeds where logging like this is equally useful.

Finally, if a RPZ or custom Lua policy has been applied, response messages also contain the applied policy name and some tags. This is particularly useful to detect and act on infected hosts.

Please add support for the logging of policy names.

I just tested with the following configuration on the PowerDNS recursor

rpzFile("/etc/pdns-recursor/basic.rpz", {
  policyName="custom",
  tags={"tagA", "tagB"}
})

This enhancement will be available with the next release.
