First, nothing oslo specific is discussed here, so [oslo] tag is probably  
redundant.

Overall, I believe you try to rely on wrong thing that won’t deliver for  
you: callbacks are internal to neutron-server, so events triggered by  
neutron-servers will never reach any other processes (like your agent).
