[MINOR] http: disable keep-alive when process is going down

Browse Source 
Krzysztof Oledzki suggested to disable keep-alive when a process
is going down due to a reload, in order to avoid ever-lasting
sessions. This is a simple and very efficient solution as it
ensures that at most one more request will be handled on a
keep-alive connection after the process has received a SIGUSR1
signal.
