Though labels compressor is quite resource intensive, each aggregator

(cherry picked from commit 6b493582da)
The new flag type is supposed to be used for specifying URL values which
could contain sensitive information such as auth tokens in GET params or
HTTP basic authentication.
The URL flag also allows loading its value from files if `file://`
prefix is specified. As example, the new flag type was used in
app/vmbackup as it requires specifying `authKey` param for making the
snapshot.

(cherry picked from commit 5f487c7090)
This speeds up auto-suggestion for metric names in VMUI and Grafana, which use the following query in this case:
/api/v1/label/__name__/values?match[]={__name__=~"*.some_value.*"}
When the user types `some_value` in the query input field.
* app/vmauth: do not increment backend_errors when hitting concurrency limit
Previously, both "vmauth_concurrent_requests_limit_reached_total" and "vmauth_user_request_backend_errors_total" were incremented.
This was based on the assumption that if concurrency limit is hit the backend must be failing to handle the request thus meaning an error.
This assumption does not work in case the endpoint can be overloaded by the misbehaving client sending too many requests within the timeframe.

- 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.

- Allow specifying only a single HTTP header for reading auth tokens via -httpAuthHeader command-line flag.
This is better from security PoV, since this prevents from accidental reading of auth token from undesired
HTTP header. By default the -httpAuthHeader equals to Authorization. When it is overridden, then
auth token isn't read from Authorization header - it is read only from the specified header.
- Document the -httpAuthHeader command-line flag at https://docs.victoriametrics.com/vmauth/#reading-auth-tokens-from-other-http-headers
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6009
This reverts commit cb23685681.
Reason for revert: the "fix" may hide programming bugs related to incorrect creation of folders
before their use. This may complicate detecting and fixing such bugs in the future.
There are the following fixes for the issue https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5985 :
- To configure the OS to do not drop data from the system-wide temporary directory (aka /tmp).
- To run VictoriaMetrics with -cacheDataPath command-line flag, which points to the directory,
which cannot be removed automatically by the OS.
The case when the user accidentally deletes the directory with some files created by VictoriaMetrics
shouldn't be considered as expected, so VictoriaMetrics shouldn't try resolving this case automatically.
It is much better from operation and debuggability PoV is to crash with the clear `directory doesn't exist` error
in this case.
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.
This is a follow-up for 02bccd1eb9
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5900
Custom HTTP headers are set via net/http.Header.Set or net/http.Header.Add functions.
These functions always convert header keys to canonical form. So the change at b577413d3b
isn't visible to users of VictoriaMetrics components.
There is no need in documenting this change at docs/CHANGELOG.md, since it doesn't give any useful information to users.

Signed-off-by: Zakhar Bessarab <z.bessarab@victoriametrics.com>
* lib/storage: consistently use MaxTimestamp to determine deduplication/downsampling rules
Using MinTimestamp leads to applying downsampling to parts which are only partially covered by downsampling rule.
For example, partition covers range [1000-2000]. At t=2100 and rule offset 500 data with t=2100-500 => 1600 must be downsampled. The range check against MinTimestamp evaluates to true even though partition contains range which must not be downsampled - [1600:2000].
Signed-off-by: Zakhar Bessarab <z.bessarab@victoriametrics.com>
* Follow-up
- Apply the first matching downsampling period if multiple filters match the given time series.
This allows fine-tuning the downsampling config for the specific needs.
- Take into account downsampling filters during search queries.
- Reduce the difference between community and enterprise branches. This should simplify further maintenance of these branches.
- Properly parse series filters with colons inside them.
- Document the feature at docs/CHANGELOG.md.

During shutdown period of vmalert, remotewrite client retrieve all pending time series from buffer queue, compose them into 1 batch and execute remote write.
This final batch may exceed the limit of -remoteWrite.maxBatchSize, and be rejected by the receiver (gateway, vmcluster or others).
This changes ensures that even during shutdown vmalert won't exceed the max batch size limit for remote write
destination.
