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.

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

all: subsitute ioutil.ReadAll with io.ReadAll

Add ability to sign requests for all AWS services (#2604) 
This adds the ability to utilize sigv4 signing for all AWS services not
just "aps". When the newly introduced property "service" is not set it
will default to "aps".

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

lib/promscrape: store the full response in stream parsing mode in scrapeWork.lastScrape byte slice 
This allows sending staleness marks and properly calculate scrape_series_added metric in stream parsing mode
at the cost of the increased memory usage, since now the potentially big response is kept
in the lastScrape byte slice per each scrapeWork.

In practice the memory usage increase shouldn't be big, since the response size
is usually much smaller than the parsed metrics from this response after the relabeling,
which usually adds a big pile of target-specific labels per each metric.

09670479cd lib/promscrape: reduce CPU usage for common case when calculating scrape_series_added metric 
Also reduce CPU usage when applying `series_limit` to scrape targets with constant set of metrics.

The main idea is to perform the calculations on scrape_series_added and series_limit
only if the set of metrics exposed by the target has been changed.
Scrape targets rarely change the set of exposed metrics,
so this optimization should reduce CPU usage in general case.

67bc407747 lib/promscrape: reduce memory and CPU usage when Prometheus staleness tracking is enabled for metrics from deleted / disappeared scrape targets 
Store the scraped response body instead of storing the parsed and relabeld metrics.
This should reduce memory usage, since the response body takes less memory than the parsed and relabeled metrics.
This is especially true for Kubernetes service discovery, which adds many long labels for all the scraped metrics.

This should also reduce CPU usage, since the marshaling of the parsed
and relabeld metrics has been substituted by response body copying.

027607db3e lib/promscrape/discovery/kubernetes: refresh endpoints and endpointslices scrape targets every 5 seconds, since they may depend on changed service and pod objects 
This should make endpoints and endpointslices scrape targets eventually consistent with the maximum delay of 5 seconds after the related service or pod object changes.

e6c19cb09d lib/promscrape/discovery/kubernetes: start watchers for pods and services before starting watchers for endpoints 
This should eliminate possible race when an update on endpoints depends on pods and/or services, which are missing in the cache yet.
This could result in missing targets based on endpoints or endpointslices.

421a92983a lib/promscrape/discovery/kubernetes: remove a mutex at urlWatcher - use groupWatcher mutex for accessing all the urlWatcher children 
This simplifies the code a bit and reduces the probability of improper mutex handling and deadlocks.

9da2ef3d8f lib/promscrape/discovery/kubernetes: load objects missing in local cache from api seriver in getObjectByRole() 
This should fix possible race for `role: endpoints` and `role: endpointslices` service discovery,
when the referred `pod` and `service` objects aren't propagated to urlWatcher cache yet.

See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1182#issuecomment-813353359 for details.

fe084fdd33 lib/promscrape/discovery/kubernetes: synchronously load Kubernetes objects on first access 
Remove async registration of apiWatchers, since it breaks discovering `role: endpoints` and `role: endpointslices` targets,
which depend on pod and service objects.

There is no need in reloading `endpoints` and `endpointslices` targets if the referenced `pod` or `service` objects change,
since in this case the corresponding `endpoints` and `endpointslices` objects should also change because they contain
ResourceVersion of the referenced `pod` or `service` objects, which is modified on object update.
