Rudder

In the parent task, we added "ulimit -v unlimited" in a patch for script "/opt/rudder/jetty7/bin/jetty-sles.sh" but:

- the patch is not applied, so currently an install does not have it,
- and EVEN with the patch, the parent bug is not corrected.

To correct parent task, we need to add "ulimit -v unlimited" in `/etc/init.d/rudder-jetty`:

usage()
{
    echo "Usage: ${0##*/} [-d] {start|stop|run|restart|check|supervise} [ CONFIGS ... ] " 
    exit 1
}

[ $# -gt 0 ] || usage

ulimit -v unlimited
