Devstack does not set the "gateway_external_netword_id" to null when "external_network_bridge" is set to null. They both should be set to null in the l3_agent.ini when a single agent supports multiple external network

[Swaminathan Vasudevan]

When multiple external networks are set for the provider network, the l3_agent.ini should have

external_network_bridge = ""
gateway_external_network_id = ""

if a single agent is hosting all the multiple external networks.

In devstack today, when there is no 'br-ex' configured, the devstack "stack.sh" script only configures external_network_bridge="" and not gateway_external_network_id.

This causes some issues in validation. Because there is a check to make sure if the "gateway_external_network" is null or not. If the key is not found, the action varies.
