What this PR does / why we need it:

Limiting the cardinality on labels hides a lot of useful information. This PR removes these limits for now.

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

I'm fine with this, though if it were a request parameter it would give us more flexibility to find the right balance in the future. But, let's nuke it for now and see if it becomes a problem.
