BigSwitch plugin: missing keyword in router rules

[Kevin Benton]

In this BigSwitch plugin router rules support, the plugin only accepts the 'any' keyword. However, it should accept both the 'external' keyword as well, which looks the same to neutron (0.0.0.0/0) but has a different meaning on the backend controller.
