> This is a component of the slave that informs the slave about the possible "corrections" that need to be performed (e.g., shutdown container using recoverable resources).
> This needs to be integrated with the resource monitor.
> Need to figure out the metrics used for sending corrections (e.g., scheduling latency, usage, informed by executor/scheduler)
> We also need to figure out the feedback loop between the QoS controller and the Resource Estimator.

>   QoSController(ResourceMonitor* monitor);
>   process::Queue<QoSCorrection> correction();
