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.
