Vladyslav Diachenko 821c0b1ae0 DequeueMany fix (#11797) ... **What this PR does / why we need it**: Previously we relied only on the index of the tenant's queue to read the requests from the same tenant's queue. However, as long as the queue is aggressively used by the consumers in parallel, there are a few edge cases when knowing the index of last used tenant's queue is not enough to guarantee that we dequeue items from exactly the same tenant's queue. **Special notes for your reviewer**: **Checklist** - [ ] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - [ ] Documentation added - [x] Tests updated - [ ] `CHANGELOG.md` updated - [ ] If the change is worth mentioning in the release notes, add `add-to-release-notes` label - [ ] Changes that require user attention or interaction to upgrade are documented in `docs/sources/setup/upgrade/_index.md` - [ ] 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`. [Example PR](d10549e3ec) - [ ] If the change is deprecating or removing a configuration option, update the `deprecated-config.yaml` and `deleted-config.yaml` files respectively in the `tools/deprecated-config-checker` directory.
