Bug description:
  Hi all,

  There is no quota for allowed address pair, user can create unlimited
  allowed address pair, in the backend, there will be at least 1
  iptables rule for one allowed address pair.  I tested if we use the
  attachment script to add about 10,000 allowed address pair. It will
  cost 30 sec to reflesh iptables rules in kernel...  I think that bad
  man can use this api to attack compute nodes. This will make the
  compute nodes crash or very slow only if we add enough allowed address
  pair rules...

  Thanks.
