    Raise number of nailgun uWSGI workers and sockets

    Fixes issue where nailgun stops responding to requests
    because all workers are occupied and the queue of
    available uWSGI sockets fills up by increasing the
    number of workers (double) and raising the connection
    limit from 100 to 4096.

    This requires a kernel setting of net.core.somaxconn, which
    is now being applied on Fuel Master host because it cannot
    be done on an unprivileged Docker container.
