> Slave might want to kill revocable tasks based on correction events from the QoS controller.
> The QoS controller communicates corrections through a stream (or process::Queue) to the
slave which corrections it needs to carry out, in order to mitigate interference with production
tasks.
> The correction is communicated through a message:
> [code]
> message QoSCorrection {
>      enum CorrectionType {
>          KillExecutor = 1
>          // KillTask = 2
>          // Resize, throttle task
>      }
> optional string reason = X;
> optional ExecutorID executor_id = X;
> // optional TaskID task_id = X;
> }
> [/code]
> And the slave will setup a handler to process these events. Initially, only executor
termination is supported and cause the slave to issue 'containerizer->destroy()'.
