Aliaksandr Valialkin	9fbd45a22f	lib/promscrape/discovery/kuma: follow-up for 317fef95f9 ... - Do not generate __meta_server label, since it is unavailable in Prometheus. - Add a link to https://docs.victoriametrics.com/sd_configs.html#kuma_sd_configs to docs/CHANGELOG.md, so users could click it and read the docs without the need to search the corresponding docs. - Remove kumaTarget struct, since it is easier generating labels for discovered targets directly from the response returned by Kuma. This simplifies the code. - Store the generated labels for discovered targets inside atomic.Value. This allows reading them from concurrent goroutines without the need to use mutex. - Use synchronouse requests to Kuma instead of long polling, since there is a little sense in the long polling when the Kuma server may return 304 Not Modified response every -promscrape.kumaSDCheckInterval. - Remove -promscrape.kuma.waitTime command-line flag, since it is no longer needed when long polling isn't used. - Set default value for -promscrape.kumaSDCheckInterval to 30s in order to be consistent with Prometheus. - Remove unnecessary indirections for string literals, which are used only once, in order to improve code readability. - Remove unused fields from discoveryRequest and discoveryResponse. - Update tests. - Document why fetch_timeout and refresh_interval options are missing in kuma_sd_config. - Add docs to discoveryutils.RequestCallback and discoveryutils.ResponseCallback, since these are public types. Side notes: it is weird that Prometheus implementation for kuma_sd_configs sets `instance` label, since usually this label is set by the Prometheus itself to __address__ after the relabeling phase.
