Since this is used for other things than filesystems, how about moving it
to `org.apache.flink.core.util`?

>
> Streams that are opened through {{FileSystem}} must be closed at the end of
> their life cycle. However, we found hints that some code forgets to close
> such streams.
> We should introduce i) a mechanism that closes leaking unclosed streams after
> usage and ii) provides logging that helps us to track down and fi the sources
> of such leaks.
