   Currently `ObjectStore::put` accepts a `Bytes` object, which is a contiguous memory region. This is simple and efficient where payload sizes are known ahead of time, and buffers can therefore be sized appropriately up-front, however, it may force additional copies in situations where this is not known.
   
   **Describe the solution you'd like**
   <!--

   I am not sure, the HTTP-based stores are fairly coupled to HTTP requests containing a `Bytes` body, and whilst `reqwest` does have the ability to wrap a byte stream, this would break retries, AWS content signing and possibly some other things.
   
   **Describe alternatives you've considered**
   <!--
   A clear and concise description of any alternative solutions or features you've considered.

   With #5500 it becomes possible to do chunked writes with no additional copies, this potentially reduces the need for this functionality as users can just allocate data in 5 MiB chunks.
   
   **Additional context**
   <!--
   Add any other context or screenshots about the feature request here.
   -->
   
   https://github.com/apache/arrow-rs/pull/5500 adds a put_part API with a similar requirement
