What this PR does / why we need it:
Adds a new --include-common-labels flag to logcli query, which causes the output to include all common labels.

This is mostly useful with --quiet and --output=jsonl as it allows users to get structured information from Loki that has all the information that Loki can provide.

Which issue(s) this PR fixes:
Fixes #5702

Special notes for your reviewer:

  • The suggestion on the PR was --all-labels. Given there are other label selection options, I thought it was easiest to add something to directly control the behaviour to remove common labels.
  • I have not written tests, but I have verified that it works locally

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
  • 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

Adds a new `--include-common-labels` flag to `logcli query`,
which causes the output to include all common labels.

This is mostly useful with `--quiet` and `--output=jsonl`
as it allows users to get structured information from Loki
that has *all* the information that Loki can provide.

Fixes grafana#5702
