Public bug reported:

When logged in as a demo tenant from Horizon, I created a Network N1 with subnet CIDR address of 10.10.10.0/24 that got created successfully. Next, i create a Network N2 with the same subnet CIDR address of 10.10.10.0/24 expecting an error message indicating that a network with the subnet CIDR address of 10.10.10.0/24 already exists., however, the network got created successfully. 
It is understandable that two networks with the same subnet CIDR address can exists across different tenants in the same OpenStack instance. However, curious as to what the use case or rationale would be for allowing two networks within the same tenant to be allowed to be created with the same subnet CIDR address?
