Example server for testing

Basic call (always creates fresh traces):

```sh
curl 'http://127.0.0.1:3000/' -i
```

Call with parent trace (check request and response headers, trace ID should match):

```sh
curl 'http://127.0.0.1:3000/' -H 'traceparent: 00-00110022003300440055006600770088-0011223344556677-01' -i
```
