lib/promscrape/discovery/kubernetes: do not generate targets for already terminated pods and containers
...
Already terminated pods and containers cannot be scraped and will never resurrect,
so there is zero sense in creating scrape targets for them.

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.

lib/promscrape/discovery/kubernetes: use a single watcher per apiURL
...
Previously multiple scrape jobs could create multiple watchers for the same apiURL. Now only a single watcher is used.
This should reduce load on Kubernetes API server when many scrape job configs use Kubernetes service discovery.
