lib/promscrape: disable support for service discovery and metrics scrape via http2
...
Reasons for disabling http2:
- http2 is used very rarely comparing to http for Prometheus metrics exposition and service discovery
- http2 is much harder to debug than http
- http2 has very bad security record because of its complexity - see https://portswigger.net/research/http2
VictoriaMetrics components are compiled with nethttpomithttp2 tag because of these issues.

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.
