Remove TLD @Parameter from inside the DnsMetrics

Browse source 
Currently, the TLD is a "hidden" part of the metric - we record it, but by looking at the call site you can't see that we record it.

Also, it's injected from the query / POST parameter, so we might not even be aware of what the value is and it might not be the value we wanted.

Instead, making it explicit in the Metric call. That way it's also more similar to the "logging" statements that record the same data but have to explicitly output the TLD.

It also makes the tests better, as we test that we indeed record the correct TLD
