> When the agent is upgraded, it will need to re-persist resources for recovered active tasks and executors, but with Resource.allocation_info.role set to FrameworkInfo.role.
> If this agent receives new tasks from an old master (because the master has not been upgraded yet), it will also augment the resources to have Resource.allocation_info.role set prior to persisting on disk. This is necessary to ensure we continue to charge existing tasks / executors if the framework changes its role(s).
> Importantly, re-persisting will not prevent downgrading the agent since a downgraded agent will simply ignore the unknown fields.
