[#9999] rpc: Use DeadlineExceeded error when creating stream failed by timeout

According to https://pkg.go.dev/context#pkg-variables, ContextCancelled
should be returned when the context is canceled for some reason other
than its deadline passing. So creating gRPC stream with dial timeout fits
better for context.DeadlineExceeded.
