The bulk of this change looks related to parallel iteration, not parallel
deserialization and consumption. I would recommend:
1. Initial PR to implement general purpose serial iteration with
deserialization and consumption pushed off to a thread pool.
2. If benchmarks show significant improvements, add support for
parallelizing the iteration step using a different thread pool from the
consumers.
- This would probably be good to expose as a parallel stream, for
example by implementing it as a `Spliterator` and returning a stream from
[StreamSupport#stream](https://docs.oracle.com/javase/8/docs/api/java/util/stream/StreamSupport.html#stream-java.util.Spliterator-boolean-).
3. Migrate each use case to the new implementation in individual PRs
- In HDDS-11777 we would probably create a wrapper around this utility
to allow processing all locations in an FSO tree for debug or repair
efficiently cc @dombizita
