all: use Gauge instead of Counter for *_config_last_reload_successful metrics
This allows exposing the correct TYPE metadata for these labels when the app runs with -metrics.exposeMetadata command-line flag.

app/vmagent: add -enableMultitenantHandlers command-line flag
This flag allows converting tenant id to (vm_account_id, vm_project_id) labels.
this flag deprecates `-remoteWrite.multitenantURL` command-line flag,
because `-enableMultitenantHandlers` is easier to use and combine with multitenant url

app/vmagent: code cleanup for Kafka and Google PubSub consumers / producers
- Add links to relevant docs into descriptions for every -kafka.* and -gcp.pubsub.* command-line flags.
- Wait until message processing goroutines are stopped before returning from gcppubsub.Stop().
- Prevent from multiple calls to Init() without Stop().
- Drop message if tenantID cannot be parsed properly.
- Take into account tenantID for all the supported message formats.
- Support gzip-compressed messages for graphite format.
- Use exponential backoff sleep when the message cannot be pushed to remote storage systems
  because of disabled on-disk persistence - https://docs.victoriametrics.com/vmagent.html#disabling-on-disk-persistence
- Unblock from sleep as soon as Stop() is called. Previously the sleep could take up to 2 seconds after Stop() is called.
- Remove unused globalCtx and initContext from app/vmagent/remotewrite/gcppubsub
- Mention Google PubSub support at docs/enterprise.md
- Make Google PubSub docs more clear at docs/vmagent.md

app/vmagent: follow-up for 090cb2c9de
- Add Try* prefix to functions, which return bool result in order to improve readability and reduce the probability of missing check
  for the result returned from these functions.

- Call the adjustSampleValues() only once on input samples. Previously it was called on every attempt to flush data to peristent queue.

- Properly restore the initial state of WriteRequest passed to tryPushWriteRequest() before returning from this function
  after unsuccessful push to persistent queue. Previously a part of WriteRequest samples may be lost in such case.

- Add -remoteWrite.dropSamplesOnOverload command-line flag, which can be used for dropping incoming samples instead
  of returning 429 Too Many Requests error to the client when -remoteWrite.disableOnDiskQueue is set and the remote storage
  cannot keep up with the data ingestion rate.

- Add vmagent_remotewrite_samples_dropped_total metric, which counts the number of dropped samples.

- Add vmagent_remotewrite_push_failures_total metric, which counts the number of unsuccessful attempts to push
  data to persistent queue when -remoteWrite.disableOnDiskQueue is set.

- Remove vmagent_remotewrite_aggregation_metrics_dropped_total and vm_promscrape_push_samples_dropped_total metrics,
  because they are replaced with vmagent_remotewrite_samples_dropped_total metric.

- Update 'Disabling on-disk persistence' docs at docs/vmagent.md

- Update stale comments in the code

app/vmagent: allow to disabled on-disk persistence (#5088)
* app/vmagent: allow to disabled on-disk queue
Previously, it wasn't possible to build data processing pipeline with a
chain of vmagents. In case when remoteWrite for the last vmagent in the
chain wasn't accessible, it persisted data only when it has enough disk
capacity. If disk queue is full, it started to silently drop ingested
metrics.

New flags allows to disable on-disk persistent and immediatly return an
error if remoteWrite is not accessible anymore. It blocks any writes and
notify client, that data ingestion isn't possible.

Main use case for this feature - use external queue such as kafka for
data persistence.
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2110

* adds test, updates readme

* apply review suggestions

* update docs for vmagent

* makes linter happy

lib/protoparser: decrease import.maxLineLen from 100MB to 10MB (#5364)
Tests showed that importing a single line with 70MB size takes 5.3GiB
RSS memory for VictoriaMetrics single-node.
In the scenario when user exports and imports data from one VM to another,
it could possibly lead to OOM exception for destination VM.

Importing a single line with 16MB size taks 1.3GiB RSS memory.
Hence, the limit for `import.maxLineLen` was decreased from 100MB to 10MB
to improve reliability of VictoriaMetrics during imports.

app/vmagent/remotewrite: do not drop persistent queues when -remoteWrite.multitenantURL is set
It is unsafe to drop persistent queues when -remoteWrite.multitenantURL command-line flag is set,
since these queues are created on demand when a new sample for the given tenant is pushed
to the remote storage.

lib/promauth: follow-up for e16d3f5639
- Make sure that invalid/missing TLS CA file or TLS client certificate files at vmagent startup
  don't prevent from processing the corresponding scrape targets after the file becomes correct,
  without the need to restart vmagent.
  Previously scrape targets with invalid TLS CA file or TLS client certificate files
  were permanently dropped after the first attempt to initialize them, and they didn't
  appear until the next vmagent reload or the next change in other places of the loaded scrape configs.

- Make sure that TLS CA is properly re-loaded from file after it changes without the need to restart vmagent.
  Previously the old TLS CA was used until vmagent restart.

- Properly handle errors during http request creation for the second attempt to send data to remote system
  at vmagent and vmalert. Previously failed request creation could result in nil pointer dereferencing,
  since the returned request is nil on error.

- Add more context to the logged error during AWS sigv4 request signing before sending the data to -remoteWrite.url at vmagent.
  Previously it could miss details on the source of the request.

- Do not create a new HTTP client per second when generating OAuth2 token needed to put in Authorization header
  of every http request issued by vmagent during service discovery or target scraping.
  Re-use the HTTP client instead until the corresponding scrape config changes.

- Cache error at lib/promauth.Config.GetAuthHeader() in the same way as the auth header is cached,
  e.g. the error is cached for a second now. This should reduce load on CPU and OAuth2 server
  when auth header cannot be obtained because of temporary error.

- Share tls.Config.GetClientCertificate function among multiple scrape targets with the same tls_config.
  Cache the loaded certificate and the error for one second. This should significantly reduce CPU load
  when scraping big number of targets with the same tls_config.

- Allow loading TLS certificates from HTTP and HTTPs urls by specifying these urls at `tls_config->cert_file` and `tls_config->key_file`.

- Improve test coverage at lib/promauth

- Skip unreachable or invalid files specified at `scrape_config_files` during vmagent startup, since these files may become valid later.
  Previously vmagent was exitting in this case.

app/{vmagent,vminsert}: follow-up for NewRelic data ingestion protocol support
This is a follow-up for f60c08a7bd

Changes:

- Make sure all the urls related to NewRelic protocol start from /newrelic . Previously some urls were started from /api/v1/newrelic

- Remove /api/v1 part from NewRelic urls, since it has no sense

- Remove automatic transformation from CamelCase to snake_case for NewRelic labels and metric names,
  since it may complicate the transition from NewRelic to VictoriaMetrics. Preserve all the metric names and label names,
  so users could query metrics and labels by the same names which are used in NewRelic.
  The automatic transformation from CamelCase to snake_case can be added later as a special action for relabeling rules if needed.

- Properly update per-tenant data ingestion stats at app/vmagent/newrelic/request_handler.go . Previously it was always zero.

- Fix NewRelic urls in vmagent when multitenant data ingestion is enabled. Previously they were mistakenly started from `/`.

- Document NewRelic data ingestion url at docs/Cluster-VictoriaMetrics.md

- Remove superflouos memory allocations at lib/protoparser/newrelic

- Improve tests at lib/protoparser/newrelic/*

lib/license: cleanups and prettifications for log messages and docs related to licensing
- Make more clear the docs at docs/enterprise.md, so readers could figure out faster
  on how to obtain enterprise key and how to pass it to VictoriaMetrics Enterprise components.

- Fix examples at docs/enterprise.md, which were referring to non-existing `-license-file` command-line flag.
  The `-licenseFile` command-line flag must be used instead.

- Improve the description of `-license*` command-line flags, so users could understand
  faster how to use them.

- Improve the warning message, which is emitted when the deprecated -eula command-line flag is passed,
  so the user could figure out how to switch faster to -license* command-line flags.

- Disallow running VictoriaMetrics components with both -license and -licenseFile command-line flags.

- Disallow running VictoriaMetrics components when -licensFile points to an empty file.

- Consistently use the phrase "This flag is available only in Enterprise binaries" across
  all the enterprise-specific command-line flags.

- Remove unneeded level of indirection for `noLicenseMessage` and `expiredMessage` string contants
  in order to improve code readability and maintainability.

- Remove unneded `return` statements after `logger.Fatalf()` calls, since these calls exit the app and never return.

- Make sure that the info log message about successful license verification is emitted
  when the license is verified successfully. Previously the error message could be logged
  when the license payload is invalid or if it misses some required features.

lib/promscrape: make concurrency control optional (#5073)
* lib/promscrape: make concurrency control optional

Before, `-maxConcurrentInserts` was limiting all calls to `promscrape.Parse`
function: during ingestion and scraping. This behavior is incorrect.
Cmd-line flag `-maxConcurrentInserts` should have effect onl on ingestion.

Since both pipelines use the same `promscrape.Parse` function, we extend it
to make concurrency limiter optional. So caller can decide whether concurrency
should be limited or not.

This commit makes c53b5788b4
obsolete.

app/vmagent/remotewrite: follow-up after a27c2f3773
- Fix Prometheus-compatible naming after applying the relabeling if -usePromCompatibleNaming command-line flag is set.
  This should prevent from possible Prometheus-incompatible metric names and label names generated by the relabeling.
- Do not return anything from relabelCtx.appendExtraLabels() function, since it cannot change the number of time series
  passed to it. Append labels for the passed time series in-place.
- Remove promrelabel.FinalizeLabels() call after adding extra labels to time series, since this call has been already
  made at relabelCtx.applyRelabeling(). It is user's responsibility if he passes labels with double underscore prefixes
  to -remoteWrite.label.
