> Provide state reconciliation for frameworks.

> Key: MESOS-1407

> Project: Mesos
> Issue Type: Epic

> State inconsistencies can arise between the framework scheduler's view of
> tasks and the view of tasks within Mesos.
> Frameworks, like Aurora, have had to compensate for these inconsistencies by
> running a specialized executor on the slave that reconciles what happened on
> the slave against what the scheduler thinks is the current state of tasks.
> This ticket is to track ways to allow frameworks to detect state
> inconsistencies both when:
> (1) There are tasks known to the framework, but unknown to Mesos. This can
> arise when the framework's intent was not carried out, or when a terminal
> event is not delivered to the framework.
> (2) There are tasks known to Mesos but unknown to the framework. This can
> arise when the framework suffered information loss, _assuming the framework
> always persists its intent prior to taking an action_.
> We have recently added a reconciliation message that allows frameworks to
> deal with (1), but nothing for (2) just yet. This could be accomplished using
> an "implicit" form of the same reconciliation message, or we could consider
> providing a way for frameworks to receive a full list of the tasks, which
> allows them to reconcile both (1) and (2).
