> Components: controller

>
> Currently controller appends the requests to brokers into controller channel
> manager queue during state transition. i.e. the state transition are
> propagated asynchronously. We need to track the request queue time on the
> controller side to see how long the state propagation is delayed after the
> state transition finished on the controller.
