Bryan Boreham f89a51fde8 Tracing: elide small traces for Stats call (#10308) ... **What this PR does / why we need it**: At work I see a lot of traces getting data dropped due to being tens of megabytes in size. Looking at what was captured, I see many many repeats of these four spans: <img width="1070" alt="image" src="https://github.com/grafana/loki/assets/8125524/4268e664-6910-49bb-8f68-69b139a5a66b"> Events on the parent trace are cheaper and, for small operations like this, just as useful. Where there was an event line I added a `function` field matching the previous span name. For `storeEntry.Stats()` I didn't add an event line as it doesn't seem to do very much. But please correct me; I'm not hugely familiar with the Loki codebase. **Special notes for your reviewer**: **Checklist** - [x] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - NA Documentation added - NA Tests updated - [x] `CHANGELOG.md` updated - NA If the change is worth mentioning in the release notes, add `add-to-release-notes` label - NA Changes that require user attention or interaction to upgrade are documented in `docs/sources/setup/upgrade/_index.md` - NA For Helm chart changes bump the Helm chart version in `production/helm/loki/Chart.yaml` and update `production/helm/loki/CHANGELOG.md` and `production/helm/loki/README.md`.
