Deletes a chunked upload.

Deletes a chunked upload that has been committed but not yet consumed.

This method cannot be used to delete the following types of chunked uploads, which the system deletes automatically:

• Chunked uploads that have been consumed by use in another API call.
• Expired chunked uploads.

Note: If you are aware of a chunked upload that can be discarded, the best practice is to explicitly delete it. If you wait for the system to automatically delete it after it expires, the chunked upload will continue to count against your quota.
