Norman Maurer cb139043f3 [#5831] HttpServerCodec cannot encode a respons e to HEAD
request with a 'content-encoding: chunked' header

Motivation:

It is valid to send a response to a HEAD request that contains a transfer-encoding: chunked header, but it is not valid to include a body, and there is no way to do this using the netty4 HttpServerCodec.

The root cause is that the netty4 HttpObjectEncoder will transition to the state ST_CONTENT_CHUNK and the only way to transition back to ST_INIT is through the encodeChunkedContent method which will write the terminating length (0\r\n\r\n\r\n), a protocol error when responding to a HEAD request

Modifications:

- Keep track of the method of the request and depending on it handle the response differently when encoding it.
- Added a unit test.

Result:

Correclty handle HEAD responses that are chunked.
