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/discovery/consulagent: substitute metaPrefix with the __meta_consulagent_ plaintext string
...
This simplifies future code navigation and search for the specific meta-label starting from __meta_consulagent_* prefix.
For example, `grep __meta_consulagent_namespace` finds the exact place where this label is defined.

lib/promscrape/discovery/nomad: follow-up after 48f371a46c
...
- Remove undocumented `username` and `password` config options from `nomad_sd_config`.
TODO: probably, remove these options from `consul_sd_config` too?
These options exist there for backwards compatibility purposes.
- Add __meta_nomad_service_alloc_id and __meta_nomad_service_job_id meta-labels
These labels contain AllocID and JobID fields for the discovered Nomad services.
- Various typo fixes.

all: use os.{Read|Write}File instead of ioutil.{Read|Write}File
...
The ioutil.{Read|Write}File is deprecated since Go1.16 -
see https://tip.golang.org/doc/go1.16#ioutil
VictoriaMetrics needs at least Go1.18, so it is safe to remove ioutil usage
from source code.
