69004a5f67 lib/promscrape: fix tests after the commit 658a8742ac
The original commit copies `__address__` label to `instance` label when generating per-target labels as Prometheus does.

See https://www.robustperception.io/life-of-a-label for details.

6a75c95194 lib/promscrape: remove labels starting with __meta_ after applying relabel_configs as Prometheus does
This should reduce CPU load during scraping when target discovery generates
big number of `__meta_*` labels (for instance, k8s discovery).

See https://www.robustperception.io/life-of-a-label for details.
