18c2075159 lib/promscrape: remove vm_promscrape_scrapes_failed_per_url_total and vm_promscrape_scrapes_skipped_by_sample_limit_per_url_total metrics
These metrics may result in big number of time series when vmagent scrapes thousands of targets and these targets constantly changes.

* It is better using `up == 0` query for determining failing targets.
* It is better using the following query for determining targets with exceeded limit on the number of metrics:

  scrape_samples_scraped > 0 if up == 0

38188e1d6b lib/promscrape: store ScrapeWork items by pointer in the slice returned from get*ScrapeWork()
This should prevent from possible 'memory leaks' when a pointer to ScrapeWork item stored in the slice
could prevent from releasing memory occupied by all the ScrapeWork items stored in the slice when they
are no longer used.
