Motivation: Currently there is a HttpConversionUtil.addHttp2ToHttpHeaders which requires a FullHttpMessage, but this may not always be available. There is no interface that can be used with just Http2Headers and HttpHeaders. Modifications: - add an overload for HttpConversionUtil.addHttp2ToHttpHeaders which does not take FullHttpMessage Result: An overload for HttpConversionUtil.addHttp2ToHttpHeaders exists which does not require FullHttpMessage.
