Well, the bug is valid: we should make sure that after
max_fixed_ips_per_port or quota_subnet subnets (whichever is smaller),
the server tells you you run out of subnet you can create. Quota
enforcement already works, but we don't validate the # of subnets
against max_fixed_ips_per_port

Title:
too many subnet-create cause q-dhcp failure
Status in neutron:
In Progress
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.
