app/vmagent/remotewrite: follow-up for 166b97b8d0 and b6bd9a97a3
- Make the configuration more clear by accepting the list of ignored labels during sharding
  via a dedicated command-line flag - -remoteWrite.shardByURL.ignoreLabels.
  This prevents from overloading the meaning of -remoteWrite.shardByURL.labels command-line flag.

- Removed superfluous memory allocation per each processed sample if sharding by remote storage is enabled.

app/vmagent: properly shutdown when -maxIngestionRate limit is reached
The remotewrite.Stop() expects that there are no pending calls to TryPush().
This means that the ingestionRateLimiter.Register() must be unblocked inside TryPush() when calling remotewrite.Stop().
Provide remotewrite.StopIngestionRateLimiter() function for unblocking the rate limiter before calling the remotewrite.Stop().

While at it, move the rate limiter into lib/ratelimiter package, since it has two users.
Also move the description of the feature to the correct place at docs/CHANGELOG.md.
Also cross-reference -remoteWrite.rateLimit and -maxIngestionRate command-line flags.

[vmagent] added ingestion rate limiting with new flag -maxIngestionRate (#5900)
* [vmagent] added ingestion rate limiting with new flag `-maxIngestionRate`. This flag can be used to limit the number of samples ingested by vmagent per second. If the limit is exceeded, the ingestion rate will be throttled.

lib/httpserver: return back the default value for -http.connTimeout to 2 minutes
It has been appeared that there are VictoriaMetrics users, who rely on the fact that
VictoriaMetrics components were closing incoming connections to -httpListenAddr every 2 minutes
by default. So let's return back this value by default in order to fix the breaking change
made at d8c1db7953 .

lib/promscrape: use the standard net/http.Client instead of fasthttp.Client for scraping targets in non-streaming mode
While fasthttp.Client uses less CPU and RAM when scraping targets with small responses (up to 10K metrics),
it doesn't work well when scraping targets with big responses such as kube-state-metrics.
In this case it could use big amounts of additional memory comparing to net/http.Client,
since fasthttp.Client reads the full response in memory and then tries re-using the large buffer
for further scrapes.

Additionally, fasthttp.Client-based scraping had various issues with proxying, redirects
and scrape timeouts like the following ones:

- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1945
- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5425
- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2794
- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1017

This should help reducing memory usage for the case when target returns big response
and this response is scraped by fasthttp.Client at first before switching to stream parsing mode
for subsequent scrapes. Now the switch to stream parsing mode is performed on the first scrape
after reading the response body in memory and noticing that its size exceeds the value passed
to -promscrape.minResponseSizeForStreamParse command-line flag.

Examples:

2) -metricsAuthKey=file://./relative/path/to/file - reads flag value from the given relative filepath
3) -metricsAuthKey=http://some-host/some/path?query_arg=abc - reads flag value from the given url

The flag value is automatically updated when the file contents changes.

docs: remove slug from Grafana dashboard URLs
Each Grafana dashboard has unique ID which can be used to fetch the dashboard
from grafana.com: https://grafana.com/grafana/dashboards/11176
The same dashboard can be accessed via URL with slug: https://grafana.com/grafana/dashboards/11176-victoriametrics-cluster/
But using slug implies that any change to dashboard name will break the link.
So it is better to just use ID, so the dashboard URL will never break.

This commit improves debuggability of targets in cluster mode by providing a list of -promscrape.cluster.memberNum
values per each target at /service-discovery page, which has been dropped becasue of sharding,
e.g. if this target is scraped by other vmagent instances in the cluster.
