Review comment:
I think we want to return false here for exitCausedByApp since these don't
seem to be issues with the App. From the comment in the yarn code: // Neither
the app's fault nor the system's fault. This happens by design,
// so no need for skipping nodes
If we mark it as true then it counts against our task failure, if its false
it doesn't seems like these shouldn't count against our failures.
