> Zameer has created a new driver implementation around V1Mesos (https://reviews.apache.org/r/57061). 
> The V1 Mesos code requires a Scheduler callback with a different API. To maximize code reuse, event handling logic was extracted into a [MesosCallbackHandler | https://github.com/apache/aurora/blob/master/src/main/java/org/apache/aurora/scheduler/mesos/MesosCallbackHandler.java#L286] class. However, we do not have the metrics for handling task status update in this class.
> Metrics around task status update are key performance indicators for the scheduler. We need to add the metrics back, in order to switch to V1Mesos driver in production.
