Big Switch - ML2 external attachment for vlan_switch type

https://blueprints.launchpad.net/neutron/+spec/bsn-ml2-ext-attach

This spec is to add the ability for the Big Switch ML2 driver to configure external attachment points for the vlan_switch type.

Problem description

Once the external attachment point extension[1] is implemented, ML2 drivers will have the ability to bind external attachment points to neutron networks. Since the Big Switch backend has full control over the fabric, it can bind physical ports to neutron networks. However, the code needs to be added in the ML2 driver to take these calls and pass them to the backend controller.

Proposed change

Add the appropriate external attachment methods to the Big Switch ML2 driver to relay the information to the backend controller.
