Handle the situation when remote server returns Connection: close 

after several pipelined requests.

We call Request::setMaxPipelinedRequest(1) if Connection: close is
received. Also call Request::supportsPersistentConnection(true) and
Request::setMaxPipelinedRequest(1) when closing the connection.
