lib/promscrape: optimize service discovery speed
- Return meta-labels for the discovered targets via promutils.Labels
  instead of map[string]string. This improves the speed of generating
  meta-labels for discovered targets by up to 5x.

- Remove memory allocations in hot paths during ScrapeWork generation.
  The ScrapeWork contains scrape settings for a single discovered target.
  This improves the service discovery speed by up to 2x.
