API allows overlapping CIDRs on a network

[Salvatore Orlando]

Quantum API does not check that distinct CIDRs in the same network do not overlap.
This might cause duplicated IP addresses within a given network, which is probably not desiderable.

Please ignore this bug if this was the intended behaviour.

Agreed that this is something we should enforce and express in the API v2 spec.
