lib/promscrape: properly apply series limit
Fix the following issues:

- Series limit wasn't applied when staleness tracking was disabled.
- Series limit didn't prevent from sending staleness markers for new series exceeding the limit.

Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3660

Thanks to @hagen1778 for the initial attempt to fix the issue

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: implement target-level and metric-level relabel debugging
Target-level debugging is performed by clicking the 'debug' link at the corresponding target
on either http://vmagent:8429/targets page or on http://vmagent:8428/service-discovery page.

Metric-level debugging is perfromed at http://vmagent:8429/metric-relabel-debug page.

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
Sort labels explicitly after calling the ParsedConfigs.Apply() when needed.

This reduces CPU usage when performing metric-level relabeling, where labels' sorting isn't needed.

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
