The spec mentions at least 2 reasons to send this: when another controller
asks for a role change and when the configuration of the switch has changed.
For the first one I've done an implementation on the previous hackathon.
However, I don't see how can we change the role of a controller locally.
The database is updated with the OpenFlow connection state. Do we also
need to add an option to do this in reverse ?
