* any status code from the range 200-299 from alertmanager to vmalert is not considered an error from now on (#6110)
* add changelog
(cherry picked from commit 7308bad777)
- Automatically reload changed TLS root CA pointed by -remoteWrite.tlsCAFile command-line flag
- Automatically reload changed TLS root CA configured via oauth2.tsl_config.ca_file option at -promscrape.config
- Document the change as a feature instead of a bug at docs/CHANGELOG.md
- Simplify the code at lib/promauth, which is responsible for reloading changed TLS root CA files.
- Simplify the usage of lib/promauth.Config.NewRoundTripper() - now it accepts the base http.Transport
instead of a callback, which can change the internal http.Transport.
- Reuse the default tls config if lib/promauth.Config doesn't contain tls-specific configs.
This should reduce memory usage a bit when tls isn't used for scraping big number of targets.
- Do not re-read TLS root CA files on every processed request. Re-read them once per second.
This should reduce CPU usage when scraping big number of targets over https.
- Do not store cert.pem and key.pem files in TestTLSConfigWithCertificatesFilesUpdate, since they can be loaded
from byte slices via crypto/tls.X509KeyPair().
- Remove obsolete comparisons of string representations for authConfig and proxyAuthConfig at areEqualScrapeConfigs().

* lib/{promauth,promscrape}: automatically refresh root CA certificates after changes on disk
Added a custom `http.RoundTripper` implementation which checks for root CA content changes and updates `tls.Config` used by `http.RoundTripper` after detecting CA change.
Client certificate changes are not tracked by this implementation since `tls.Config` already supports passing certificate dynamically by overriding `tls.Config.GetClientCertificate`.
This change implements dynamic reload of root CA only for streaming client used for scraping. Blocking client (`fasthttp.HostClient`) does not support using custom transport so can't use this implementation.

- Rename -opentelemetry.sanitizeMetrics command-line flag to more clear -opentelemetry.usePrometheusNaming
- Clarify the description of the change at docs/CHANGELOG.md
- Rename promrelabel.SanitizeLabelNameParts to more clear promrelabel.SplitMetricNameToTokens
- Properly split metric names at '_' char in promerlabel.SplitMetricNameToTokens.
- Add tests for various edge cases for Prometheus metric names' normalization
according to the code at b865505850/pkg/translator/prometheus/normalize_name.go
- Extract the code responsible for Prometheus metric names' normalization into a separate file (santize.go)

Updates https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6035
Remove description for -search.maxExportDuration and -search.maxStatusRequestDuration command-line flags
from the 'Resource usage limits' chapter, since these flags are rarely used for limiting resource usage
and they are already documented in the 'List of command-line flags' chapter.
- Fix docs for new functions at app/vmselect/graphite/functions.json
- Properly drain series lists on errors in aggregateSeriesListsGeneric() and aggregateSeriesList()
- Add links to docs for the added functions at docs/CHANGELOG.md
