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.
