Title: Variable upstream should be locally scoped

Because `upstream` is defined in the foreach loop, there should be no `@`, because the global `@upstream` is undefined. This results in an empty upstream definition:

```
upstream pino {

- server unix:/var/run/gunicorn/pino.sock fail_timeout=0;
+ server fail_timeout=0;

}
```
