    Set haproxy global connection limit

    Haproxy uses two separate maxconn values: the maxconn setting in the
    global context is used to adjust file descriptor limits and allocate
    resources, while the maxconn setting in the frontend context controls if
    additional connections are accepted on that frontend.

    This patch adds a maxconn to the global context equal to the sum of the
    connection limit on each listener. For listeners which no connection
    limit specified, we don't set this value and leave it at haproxy's
    default (2000).
