Based on [the code](https://github.com/elastic/elasticsearch/blob/master/server/src/main/java/org/elasticsearch/action/bulk/Retry.java#L98-L100) that is used for retrying it seems that the ordering of items in `BulkRequest` and `BulkResponse` do not match. e.g. `BulkRequest` might contain items `foo1`, `foo2`, `foo3`... and the `BulkResponse`, if retry mechanism kicks in, might have ordering `foo3`, `foo1`, `foo2`...  
I can not find the documentation on if this is intended or it is a bug.
