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.

lib/promscrape: optimize discoveryutils.SanitizeLabelName()
...
Cache sanitized label names and return them next time.
This reduces the number of allocations and speeds up the SanitizeLabelName()
function for common case when the number of unique label names is smaller than 100k
