But this might a be bigger fix because a deployer might want to
configure that number to capped vs elastic.

Title:
  too many subnet-create cause q-dhcp failure

Status in Python client library for Quantum:
  Invalid
Status in OpenStack Quantum (virtual network service):
  New

Bug description:
  I create several subnets in my 'private' network:

  quantum subnet-create private  CIDR_{i} --verbose

  the client keeps returning success. However, after the fifth attempt,
  I see my dhcp agent spitting out nasty errors, like the one below:

  2013-05-13 15:29:46    ERROR [quantum.agent.dhcp_agent] Unable to restart dhcp.

  This happens with the ovs plugin, on master.
