Export observability traces from Spice into Zipkin

In addition to the built-in `runtime.task_history` SQL table, Spice can export the observability traces it collects into Zipkin.

![The Zipkin 'Find a trace' page lists 10 single-span traces, longest first. Most traces come from the zipkin\_tracing service, with sql\_query or accelerated\_refresh root spans. Durations range from 25.829 milliseconds to 175 microseconds.](https://spice.ai/website-assets/docs/screenshot-2024-12-27-at-12-19-58-pm.png)

## Enabling Zipkin Export

Zipkin export is defined in the `spicepod.yaml` under the `runtime.tracing`section:

```yaml
runtime:
  tracing:
    zipkin_enabled: true
    zipkin_endpoint: http://localhost:9411/api/v2/spans
```

- `zipkin_enabled`: Optional. Default `false`. Enables or disables the Zipkin trace export.
- `zipkin_endpoint`: Required if `zipkin_enabled`is true. The path to the `/api/v2/spans`endpoint on the Zipkin instance to export to.
