Miek Gieben 6e466d5092 Remove dnsutil.Dedup (#1867)
Remove the code and remove the call in etcd and kubernetes handlers.
This does mean we should not add dups in the first place, which means
adding maps in backend_lookup to prevent dups from begin added.

This should cut down on the allocations because dnsutil.Dedup is very
expensive by converting everything to strings, we avoid doing that now.
