okhttp asynchronous request mode does not support collection http status

[LeePui]

skywalking java agent version : 8.9.0-SNAPSHOT
i found in synchronous call mode afterMethod，it will determine span erroreoccurred and set http.status_code according to the status code。
but in asynchronous call mode afterMethod, it just stop the span. in agent version 8.5.0, it will set erroreoccurred in OnFailureInterceptor and OnResponseInterceptor, should we add http status code collection in asynchronous call mode?

If you could read error code, then, it is better to collect the response code for all cases.
