What this PR does / why we need it:
indexStatsTripperware is used for resolving shards for most query types, but it also includes StatsCollectorMiddleware middleware in the chain which is not thread safe. This could result in data corruption of the collected stats since the subqueries split by time could resolve shards concurrently.

This pr makes changes to only include the stats collection middleware for actual index stats queries, other queries types will not need this.

Which issue(s) this PR fixes:
Fixes #

Special notes for your reviewer:

Checklist

  • Reviewed the CONTRIBUTING.md guide (required)
  • Documentation added
  • Tests updated
  • Title matches the required conventional commits format, see here
    • Note that Promtail is considered to be feature complete, and future development for logs collection will be in Grafana Alloy. As such, feat PRs are unlikely to be accepted unless a case can be made for the feature actually being a bug fix to existing behavior.
  • 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
  • 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. Example PR

Hello @ashwanthgoli!
Backport pull requests need to be either:

  • Pull requests which address bugs,
  • Urgent fixes which need product approval, in order to get merged,
  • Docs changes.

Please, if the current pull request addresses a bug fix, label it with the type/bug label.
If it already has the product approval, please add the product-approved label. For docs changes, please add the type/docs label.
If the pull request modifies CI behaviour, please add the type/ci label.
If none of the above applies, please consider removing the backport label and target the next major/minor release.
Thanks!
