Bug #1195047 This patch: 1. removes the iteration in get_ports to call extend_dict_binding 2. uses a unified way for plugins to do this kind of stuff ml2 will enhance the binding so that it can have different binding for port according to port's host. mlnx and bigswitch are also exceptions due to the dynamic binding info.
