6ec582acb9 lib/promscrape: show information on improperly configured scrape targets at the bottom of /targets page
This is a common error whith improperly configured target autodiscovery and/or relabeling.
This error leads to duplicate scraping of the same targets with the same set of labels, which leads
to duplicate samples in time series.

09f796e2ab lib/promscrape: remove labels starting with __meta_ after applying relabel_configs as Prometheus does
This should reduce CPU load during scraping when target discovery generates
big number of `__meta_*` labels (for instance, k8s discovery).

See https://www.robustperception.io/life-of-a-label for details.
