Commit 6c58091b20 was not properly ported
to the single node branch. Since single node is able to perform both
promscrape and self-scrape, it's required to add metadata add methods to
those paths.
This commit fixes missing metadata add to the storage.
Fixes https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10175
