Declare the keep-response-order obsolete
The keep-response-order option has been introduced when TCP pipelining has been introduced to BIND 9 as a failsafe for possibly non-compliant clients.
Declare the keep-response-order obsolete as all DNS clients should either support out-of-order processing or don't send more DNS queries until the DNS response for the previous one has been received.
Closes #3140 (closed)
