Description

In order for schedulers to be able to handle status updates in a scalable manner, they need the ability to send acknowledgements through the driver. This enables optimizations in schedulers (e.g. process status updates asynchronously w/o backing up the driver, processing/acking updates in batch).

Without this, an implicit reconciliation can overload a scheduler (hence the motivation for MESOS-2308).
