@ahmarsuhail
- caller provides a remote iterator, such as the ones we do for listing or
another source/transformation (see RemoteIterators)
- build() call returns some result
- implementation kicks off a worker thread to process the iterator, reading
its values in until there's enough to kick off a DELETE request (page or maybe
a parallel set in a thread pool)
- after each page/set of deletes, invokes the supplied callback of results
- then continues, unless told to stop
- finish only on: iterator has nothing, iterator raises an exception
- or maybe on reaching some limit on failures
- including maybe those considered unrecoverable
> Add API for bulk/paged object deletion

> iceberg and hbase could benefit from being able to give a list of individual
> files to delete -files which may be scattered round the bucket for better
> read peformance.
> Add some new optional interface for an object store which allows a caller to
> submit a list of paths to files to delete, where
> the expectation is
> * if a path is a file: delete
> * if a path is a dir, outcome undefined
> For s3 that'd let us build these into DeleteRequest objects, and submit,
> without any probes first.
