HttpProxy can send both Content-Length and Transfer-Encoding headers

[elunji]

Version

4.5.21 5.0.4

Context

When setting a streamable body on a ProxyResponse, a Transfer-Encoding chunked header is added, but the Content-Type header from the origin server is not removed, leading to both headers being present, which is not allowed and makes certain http client choke.

Steps to reproduce

Call ProxyResponse.setBody() and a streamable Body.

Do you have a reproducer?
