The problem was that gRPC method `status.Code(err)` doesn't unwrap errors, while Talos client returns errors wrapped with `multierror.Error` and `fmt.Errrorf`, so `status.Code` doesn't return error code correctly. Fix that by introducing our own client method which correctly goes over the chain of wrapped errors. Signed-off-by: Andrey Smirnov <smirnov.andrey@gmail.com>
