Ashwanth e915efc7f8 fix(log results cache): compose empty response based on the request (#11657) ... **What this PR does / why we need it**: Log results cache when handling a hit composes an empty response based on the cached request. But the limit or direction fields in the cached request need not match with the current request being served. This causes the log results cache to return a response with incorrect limit. This incorrect limit could then get applied when merging responses upstream (split by interval mw for ex.) This pr fixes this by composing the response based on the request being served. I also thought about updating the cache key to include both limit and direction to have a clear separation, but I left it as is for the following reason: if a time range contains no log lines, that result would not change irrespective of a different limit or direction **Which issue(s) this PR fixes**: Fixes #<issue number> **Special notes for your reviewer**: **Checklist** - [x] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - [ ] Documentation added - [x] Tests updated - [x] `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.
