Failed to start taas_plugin because of type error

[Yoichiro Iura]

I tried to use taas with devstack(master) on ubuntu 14.

But neutron failed to load taas_plugin because taas_plugin occurred type error when reading rpc.create_connection.

I think that this is related to the following bugs.

I attached logs here.
