docs: Aborts a multipart upload. After a multipart upload is aborted, no
  additional parts can be uploaded using that upload ID. The storage
  consumed by any previously uploaded parts will be freed. However, if any
  part uploads are currently in progress, those part uploads may or may not
  succeed. As a result, it may be necessary to abort a given multipart
  upload multiple times in order to completely free all storage consumed by
  all parts.
  
  @param request The AbortMultipartUploadRequest object that specifies all the parameters of this operation.
