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/promauth: follow-up after 006b8c7534
- Take into account `ca`, `key` and `cert` values when generating string representation of TLSConfig.
  Print hashes instead of real values because of security considerations.
- Properly update Config.tlsCertDigets when `key` and `cert` values are set.
  This allows properly updating scrape targets after these values are updated in configs.
- Do not re-generate certificate from `key` and `cert` values per each call to getTLSCert,
  because these values are immutable.
- Do not set `ca` value from `ca_file` value, so it isn't exposed at `/config` page.
- Generate proper error messages on incorrect `key`, `cert` or `ca` values.

lib/promscrape: properly implement ScrapeConfig.clone()
Previously ScrapeConfig.clone() was improperly copying promauth.Secret fields -
their contents was replaced with `<secret>` value.

This led to inability to use passwords and secrets in `-promscrape.config` file.
The bug has been introduced in v1.77.0 in the commit 67b10896d2
