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: properly add exported_ prefix to labels, which clash with target labels if honor_labels: true option isn't set.
The issue was in the `labels := dst[offset:]` line in the beginning of appendExtraLabels() function.
The `dst` may be re-allocated when adding extra labels to it. In this case the addition of `exported_`
prefix to labels inside `labels` slice become invisible in the returned `dst` labels.

While at it, properly handle some corner cases:

- Add additional `exported_` prefix to clashing metric labels with already existing `exported_` prefix.
- Store scraped metric names in `exported___name__` label if scrape target contains `__name__` label.

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

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
