feat(storage): Override storage class in writers to RAPID when rapid writes enabled for Pirlo Buckets

[vipnydav]

Description

This PR updates the bucket handle to explicitly set the storage class to RAPID when creating objects (via CreateObject, CreateObjectChunkWriter, and CreateAppendableObjectWriter) if rapid writes are enabled for the Pirlo bucket. By default, the storage class is left empty to use the bucket's default, but when rapid writes are enabled (PirloStateRapidWritesEnabled), the intention to write to the RAPID class is now explicitly honored.

Link to the issue in case of a bug fix.

Code Review

This pull request introduces logic to override the storage class to "RAPID" when rapid writes are enabled across various object creation methods (CreateObject, CreateObjectChunkWriter, and CreateAppendableObjectWriter), along with corresponding unit tests. The review feedback suggests avoiding direct mutation of the caller's request structs by using shallow copies instead, removing a redundant storage class override in CreateAppendableObjectWriter where it has no effect, and updating the unit tests to assert on the returned object attributes rather than the input request.
