lib/promscrape: add a link to https://docs.victoriametrics.com/vmagent.html#scraping-big-number-of-targets in descriptions for -promscrape.cluster.* command-line flags 
This should help users figuring out the purpose of -promscrape.cluster.* command-line flags

lib/promscrape: follow-up after eabcfc9bcd 
`-promscrape.cluster.membersCount` by default should be `1`, like every
single vmagent is a cluster of one member on its own.
The change additionally validates that user can't set `-promscrape.cluster.membersCount`
to value lower than `1`.

lib/promscrape: add -promscrape.cluster.memberLabel command-line flag 
This flag allows specifying an additional label to add to all the scraped metrics.
The flag must contain label name to add. The label value will be equal to -promscrape.cluster.memberNum.

This functionality can help when there is a need to differentiate metrics scraped
by distinct vmagent instances in the cluster according to https://docs.victoriametrics.com/vmagent.html#scraping-big-number-of-targets

lib/promscrape: use local scrape timestamp for scraped metrics unless honor_timestamps: true is set explicitly 
This fixes the case with gaps for metrics collected from cadvisor,
which exports invalid timestamps, which break staleness detection at VictoriaMetrics side.

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: do not re-use previously loaded scrape targets on failed attempt to load updated scrape targets at file_sd_configs 
The logic employed for re-using the previously loaded scrape target was broken initially.
The commit cc0427897c tried to fix it, but the new logic
became too complex and fragile. So it is better to just remove this logic,
since the targets from temporarily broken file should be eventually loaded on next
attempts every -promscrape.fileSDCheckInterval

This also allows removing fragile hacks around __vm_filepath label.

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.

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/promrelabel: remove unconditional sorting of the labels in ParsedConfigs.Apply(), since the sorting isnt needed in many places

lib/promscrape: allow specifying full target url in __address__ label 
Previously the `__address__` label could contain only `host:port` part of the target url,
while the scheme and metrics path were obtained from `__scheme__` and `__metrics_path__`
labels. Now it is possible to set the full url in `__address__` label.

This makes valid the following scrape config, which is frequently used by novice users:

scrape_configs:
- job_name: foo
  static_configs:
  - targets:
    - http://host1/metrics1
    - https://host2/metrics2
