    Execute ipset command using check_exit_code

    When l2 agent execute ipset command, we should pass
    parameter 'check_exit_code' to self.execute acording to
    action.
    The intention is to safely fail if we try to destroy a
    non existing set, or delete a non existing member.
    Otherwise the agent gets stuck in a loop if such situation
    happens. Such kind of event would be logged as errors.
