- Improve docs - Hide `debug relabeling` column when -promscrape.dropOriginalLabels command-line flag is set - Inline the code from the added template functions, since the code is harder to follow with the template functions, especially when these functions have misleading names. Also, these functions are used only in one place, e.g. they do not reduce the amounts of code. - Hide `click to show original labels` title at `labels` column when original labels aren't available. - Show the reason on whey original labels aren't available at /service-discovery page. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4597
