Public bug reported:

Neutron allows creation of multiple network with the same CIDR in the
same tenant

How to reproduce:
1. create 2 networks in the same tenant
2. for each create a subnet with cidr 10.0.0.0/24

Expected Result:
second subnet should raise an error

Actual Result:
subnet is created with the same cidr

ubuntu@yfried-devstack:~/devstack$ neutron subnet-list -c tenant_id -c cidr -c name --network
