Changes to allow different Neutron external networks to use the same L3Out in APIC. In the past we did not prevent such configurations, but we also did not support it properly. Changes include: * Delete L3Out only if there are no Neutron external networks using the L3Out * Disallow overlapping external subnets in external networks that share the same L3Out * Contracts consumed and provided by APIC external network should use routers uplinked to all the Neutron external networks that share an L3Out * Likewise, external CIDRs on APIC external network should consider external-cidrs of all Neutron external networks that share an L3Out Had to make minor changes to some UTs to avoid situations that now raise exceptions.
