[Feature] Display downstream error messages.

Discussed in #1065

When a downstream service has an error, it is expected to display an error message to the user.
This message might be "xx arg is invalid" and error message with trace_id.

Can you provide more details about the issue and how to reproduce? It is not clear what do you meant by downstream error. ( FYI. every API provide different error interfaces when sending error ). Also it is hard to display errors in dashboard when the plugin expects the results instead. (handling unique type of errors specific to different API is not ideal )

I hope there is a way to pass the error to the front-end page for display.

Here,we can try to parse the body and return the content using method 'errorsource.DownstreamError(err, false)' if the content is not empty.
