[1307] (unrelated) clarification cleanup: process()/putSOA()/addNXDOMAINProof()

cannot be const because they modify response_.
maybe we should pass the response via method parameter rather than at
the construction time, or even make this a simple free function, rather
than a class.  but that will be a separate discussion.
