Bug description:
Hello, I have a problem. I'm unable to add interface to router, if
previously another interface was added, from network in other subnet. There is
some confusing error message:
yar@os-controller:/opt/stack/quantum/quantum/db$ sudo quantum
--os_username=demo --os_tenant_name=demo --os_password=bf1af2bd6a80158f7827
--os_auth_url=http://localhost:35357/v2.0 router-interface-add

Subnet afb62abc-9fe1-46af-b90d-be9696c270e9 could not be found
It's confusing, because I've trying to add interface with subnet
3e159530-1397-4a3f-b380-1f7c93eb7df0, but got error about subnet
afb62abc-9fe1-46af-b90d-be9696c270e9.

So, obviously, the problem was caused by subnet overlapping check,
which iterates from all interface ports in this router, and get
subnets from it. the main problem is that it try to do this with
user's context, and subnets from other tenants was not found.
BTW, this bug leads to information disclosure about other tenant's
network ids.
