vmagent: update SD duration histogram metric if SD is active (#2677)
The change updates histogram for registering SD update duration
only SD is considered as `active`. SD is active if at least
one scraper for this SD has started.

This change supposed to reduce metrics cardinality produced
by duration histogram which gets updated even if SD isn't configured.

See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2671

fe084fdd33 lib/promscrape/discovery/kubernetes: synchronously load Kubernetes objects on first access
Remove async registration of apiWatchers, since it breaks discovering `role: endpoints` and `role: endpointslices` targets,
which depend on pod and service objects.

There is no need in reloading `endpoints` and `endpointslices` targets if the referenced `pod` or `service` objects change,
since in this case the corresponding `endpoints` and `endpointslices` objects should also change because they contain
ResourceVersion of the referenced `pod` or `service` objects, which is modified on object update.

could prevent from releasing memory occupied by all the ScrapeWork items stored in the slice when they
are no longer used.

0d44e371f3 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.
