Add a NativeHistogramBucketFactor parameter to the use of
`NewHistogramVec` in order to enable use of Prometheus Native
Histograms.
This will store automatically computed sparse buckets in CoreDNS.
If a compatible Prometeus requests native histograms this data will
returned instead of the static buckets.
The default factor of 1.05 should provide high quality resolution data.

When packing the empty domain name, miekg/dns can end up creating
corrupt DNS messages. With some planned unpacking changes, this now
trips an error condition and causes these tests to fail. Correct this
by using the root domain explicitly as this gets correctly encoded on
the wire.
