ktor-client question --- I’m trying to make an HTTP POST request with an xml body and no magic serialization, and to set the ContentType header.  I assumed I could do, e.g.

```val xmlBody: String = [prepare body]

<http://client.post|client.post>([uri]) {
    contentType(ContentType.Text.Xml)
    body = xmlBody
}```
However, I’m getting,
```io.ktor.http.UnsafeHeaderException: Header(s) [Content-Type] are controlled by the engine and cannot be set explicitly```
What’s the correct way to specify the Content-Type header, if not by explicitly calling contentType()?

The official high-level docs seem to mention using contentType() when setting up requests, so I’m a little surprised.

Figured out I could set body to a TextContent() with a contentType set on that.  Might be handy to have that in the high level docs!
