Warning: Content type detection for rest requests is deprecated

[scott-fleischman]

I'm trying out this library and I noticed the following warning being returned by Elastic. I am using Database.V5.Bloodhound and calling createIndex as in the example. Is this something that should be fixed in Bloodhound?

Response
    { responseStatus = Status
        { statusCode = 200
        , statusMessage = "OK"
        }
    , responseVersion = HTTP/1.1
    , responseHeaders =
        [
            ( "Warning"
            , "299 Elasticsearch-5.5.1-19c13d0 "Content type detection for rest requests is deprecated. Specify the content type using the [Content-Type] header." "Thu, 03 Aug 2017 23:48:20 GMT""
            )
        ,
            ( "content-type"
            , "application/json; charset=UTF-8"
            )
        ,
            ( "content-encoding"
            , "gzip"
            )
        ,
            ( "transfer-encoding"
            , "chunked"
            )
        ]
    , responseBody = "{"acknowledged":true,"shards_acknowledged":true}"
    , responseCookieJar = CJ { expose = [] }
    , responseClose' = ResponseClose
    }

Seems to be fixed in the latest release (0.15). Thanks!
