Upstream: revised upstream response time variables. Variables now do not depend on presence of the HTTP status code in response. If the corresponding event occurred, variables contain time between request creation and the event, and "-" otherwise. Previously, intermediate value of the $upstream_response_time variable held unix timestamp.
