    haproxy ns driver: set global haproxy maxconn

    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.
