bigswitch multi-tenant floating IP loss

[Kevin Benton]

The bigswitch plugin fails to use the admin context to update the floating IPs on the backend controller.
When one tenant assigns a floating IP, the update to the controller doesn't contain the floating IPs of the other tenants so the controller thinks they have been removed.
