lib/promscrape: add -promscrape.suppressDuplicateScrapeTargetErrors
command-line flag in order to suppress duplicate scrape target
errors
...
Show also original labels for duplicate targets in error message in order to simplify debugging the issue.
Now `/targets` endpoint accepts optional `show_original_labels=1` query arg, which shows original labels for each target.
This may simplify debugging for target relabeling.
