Upstream keepalive: keepalive_timeout directive.

The directive configures maximum time a connection can be kept in the
cache.  By configuring a time which is smaller than the corresponding
timeout on the backend side one can avoid the race between closing
a connection by the backend and nginx trying to use the same connection
to send a request at the same time.
