[#5866] HttpToHttp2ConnectionHandler / InboundHttp2ToHttpAdapter ignores STREAM_DEPENDENCY_ID and STREAM_WEIGHT.

Motivation:

HttpToHttp2ConnectionHandler.write(ctx, msg, promise) ignores HttpConversionUtil.ExtensionHeaderNames.STREAM_DEPENDENCY_ID header in outbound message. Beside this InboundHttp2ToHttpAdapter also not add the STREAM_DEPENDENCY_ID and STREAM_WEIGHT headers.

Modifications:

Respect STREAM_DEPENDENCY_ID and STREAM_WEIGHT

Result:

Correctly respect STREAM_DEPENDENCY_ID and STREAM_WEIGHT.
