lib/promscrape: export scrape_samples_added per-target metric like Prometheus does
...
This metric may be useful for detecting targets with high churn rate for the exported metrics.

Extend metric vm_promscrape_targets with status label ( #615 )
...
The change to `vm_promscrape_targets` metric suppose to improve observability
for `vmagent` so it will be possible to track how many targets are up or down
for every specific scrape group:
```
vm_promscrape_targets{type="static_configs", status="down"} 1
vm_promscrape_targets{type="static_configs", status="up"} 2
```

lib/promscrape: make consistent scrape time offsets across reloads for the same ScrapeURL and Labels
...
This should make consistent intervals between data points for scrape targets across reloads.
Previously these intervals were random.

`scrape_config` block from Prometheus config contains `sample_limit` field,
while in `vmagent` this field was mistakenly named as `scrape_limit`.
