The original commit copies `__address__` label to `instance` label when generating per-target labels as Prometheus does.

lib/promscrape: reload only modified scrapers on config changes

This should improve scrape stability when big number of targets are scraped and these targets are frequently changed.

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).

lib/promscrape: allow overriding external_labels as Prometheus does
...
Prometheus docs at https://prometheus.io/docs/prometheus/latest/configuration/configuration/#scrape_config say:
> In communication with external systems, they are always applied only
> when a time series does not have a given label yet and are ignored otherwise.
Though this may result in consistency chaos when scrape targets override `external_labels`,
let's stick with Prometheus behavior for the sake of backwards compatibility.
There is last resort in vmagent with `-remoteWrite.label`, which consistently
sets the configured labels to all the metrics before sending them to remote storage.
