> Recover localized resource cache state upon nodemanager restart

>
> Today when node manager restarts we clean up all the distributed cache files
> from disk. This is definitely not ideal from 2 aspects.
> * For work preserving restart we definitely want them as running containers
> are using them
> * For even non work preserving restart this will be useful in the sense that
> we don't have to download them again if needed by future tasks.
