Title:
  iptables-save command executed by "nova-manage network create" command
  with QuantumManager

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  Scenario :

  when "nova-manage network create" is executed, it internally executes "iptables-save"
  Here is a stack trace obtained by putting a breakpoint in nova/network/linux_net.py : apply() method

  
    /usr/local/bin/nova-manage(7)<module>()
  -> execfile(__file__)
    /opt/stack/nova/bin/nova-manage(1746)<module>()
  -> main()
    /opt/stack/nova/bin/nova-manage(1733)main()
  -> fn(*fn_args, **fn_kwargs)
    /opt/stack/nova/bin/nova-manage(812)create()
  -> fixed_cidr=fixed_cidr)
    /opt/stack/nova/nova/network/quantum/manager.py(223)create_networks()
  -> self.l3driver.initialize_network(cidr)
    /opt/stack/nova/nova/network/l3.py(93)initialize_network()
  -> linux_net.add_snat_rule(cidr)
    /opt/stack/nova/nova/network/linux_net.py(434)add_snat_rule()
  -> iptables_manager.apply()
    /opt/stack/nova/nova/utils.py(945)inner()
  -> retval = f(*args, **kwargs)
  > /opt/stack/nova/nova/network/linux_net.py(327)apply()
  -> current_table, _err = self.execute('%s-save' % (cmd,),

  Expected Behavior  :

  nova-manage should only touch database, because nova-manage is not always executed on nova-network node.
  So nova-manage should NOT execute iptables-save command
