[HttpStress] `HttpIOException` with `HttpRequestError=Unknown` and `QuicError=OperationAborted` on Windows

[antonfirsov]

Happened several times on Windows in POST Duplex Slow.

As a minimum, we should map this case to a better HttpRequestError if we can.

Details

System.Net.Http.HttpRequestException: Error while copying content to a stream.
 ---> System.Net.Http.HttpIOException: An error occurred while sending the request. (Unknown)
 ---> System.Net.Http.HttpRequestException: An error occurred while sending the request.

This is during cancellation: 8: POST Duplex Slow Fail: 1 Timestamps: 13:41:02.1372148, Duration: 00:00:00.0249275, Cancelled: True
We should be mapping this to OCE, there's certainly some error when handling the exception.
