Currently, 200000ms is the universal setting of request_timeout for both S3 ans Azure storage. However, the setting on S3 monitors at a more finer level - at each http request. For Azure, the setting monitors at a more granular level - at the entire API call.
It needs to be addressed, as it has created unwanted timeout in #1026. Or it needs to be dropped per #1487 (review), to rely on curl timeout completely.
