Some cleanup in proxy and dnstap: * just use time pkg directly and side step the indirection for Epoch * Use Set in SetQueryEpoch to be more Go like. (Looked like a reader) * Don't maintain two sets of time, we already track start, so use that. * Use time.Time and convert when needed * dedent the toDnstap function and put in a separate file
