Bryan Boreham 7b03796d0f Scraping: stop storing discovered labels (#15261) ... Instead of storing discovered labels on every target, recompute them if required. The `Target` struct now needs to hold some more data required to recompute them, such as ScrapeConfig. This moves the load from every Prometheus all of the time, to just when someone views Service Discovery in the UI. The way `PopulateLabels` is used changes; you are no longer expected to call it with a part-populated `labels.Builder`. The signature of `Target.Labels` changes to take a `labels.Builder` instead of a `ScratchBuilder`, for consistency with `DiscoveredLabels`. This will save a lot of work when many targets are filtered out in relabeling. Combine with `keep_dropped_targets` to avoid ever computing most labels for dropped targets.
