app/vmauth: add support for hot standby mode via first_available load balancing policy
vmauth in `hot standby` mode sends requests to the first url_prefix while it is available.
If the first url_prefix becomes unavailable, then vmauth falls back to the next url_prefix.
This allows building highly available setup as described at https://docs.victoriametrics.com/vmauth.html#high-availability

app/vmselect: properly adjust the lower bound for the time range where raw samples must be selected for default_rollup() function
Previously the lower bound could be too small, which could result in missing values at the beginning of the graph
for default_rollup() function. This function is automatically applied to all the series selectors if they aren't
explicitly wrapped into a rollup function - see https://docs.victoriametrics.com/MetricsQL.html#implicit-query-conversions

While at it, properly take into account `-search.minStalenessInterval` command-line flag when adjusting
the lower bound for the selected time range.

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/vmselect: do not limit concurrency for static and fast queries
Previously concurrency for static and fast queries was limited with the -search.maxConcurrentRequests
command-line flag. This could complicate identifying heavy queries via `vmui` at `Top queries` and `Active queries` pages,
since `vmui` and these pages couldn't be opened on overloaded vmselect.

Thanks to @f41gh7 for the idea.

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/vmselect/promql: properly handle duplicate series when merging cached results with the results obtained from the database
evalRollupFuncNoCache() may return time series with identical labels (aka duplicate series)
when performing queries satisfying all the following conditions:

- It must select time series with multiple metric names. For example, {__name__=~"foo|bar"}
- The series selector must be wrapped into rollup function, which drops metric names. For example, rate({__name__=~"foo|bar"})
- The rollup function must be wrapped into aggregate function, which has no streaming optimization.
  For example, quantile(0.9, rate({__name__=~"foo|bar"})

In this case VictoriaMetrics shouldn't return `cannot merge series: duplicate series found` error.
Instead, it should fall back to query execution with disabled cache.

Also properly store the merged results. Previously they were incorrectly stored because of a typo
introduced in the commit 41a0fdaf39

lib/htmlcomponents: use relative links for the top page and for favicon.ico
This allows hiding VictoriaMetrics components behind proxies with arbitrary path prefixes.
For example, vmagent HTTP handlers can be served via /vmagent/ path prefix:

- http://proxy/vmagent/targets
- http://proxy/vmagent/service-discovery

The path prefix can be arbitrary. For example, below are vmagent urls
for /tenantID/vmagent/ path prefix:

- http://proxy/tenantID/vmagent/targets

app/vmauth: properly pass Host header to backends
Previously the `Host` header was remained unchanged when passing it in requests to backends.
This may improperly work if the backend uses host-based routing.

While at it, allows http/2.0 requests to backends. While VictoriaMetrics components
do not accept http/2.0 requests, other backends can require such requests.

app/vmauth: follow-up for 323f3720ed
- Re-use identically configured http.Transport across multiple users.
  This fixes handling of the limit on the number of connection, which can be established per each backend
  via -maxIdleConnsPerBackend command-line flag. This limit stopped working after 323f3720ed

- Add docs about backend TLS setup at https://docs.victoriametrics.com/vmauth.html#backend-tls-setup

- Add ability to disable backend TLS verification for all the users via -backend.tlsInsecureSkipVerify command-line flag.
  This flag may be useful when -auth.config contains big number of users, and every user must disable backend TLS verification.

- Add ability to specify TLS Root CA via tls_ca_file option at per-user basis and via -backend.tlsCAFile command-line flag
  across all the users.

app/vmalert: update remote-write process (#5284)
* app/vmalert: update remote-write process

* automatically retry remote-write requests on closed connections. The change should reduce the amount of logs produced in environments with short-living connections or environments without support of keep-alive on network balancers.
* increment `vmalert_remotewrite_errors_total` metric if all retries to send remote-write request failed. Before, this metric was incremented only if remote-write client's buffer is overloaded.
* increment `vmalert_remotewrite_dropped_rows_total` amd `vmalert_remotewrite_dropped_bytes_total` metrics if remote-write client's buffer is overloaded. Before, these metrics were incremented only after unsuccessful HTTP calls.

app/vmselect/promql: optimize repeated SLI-like instant queries with lookbehind windows >= 1d
Repeated instant queries with long lookbehind windows, which contain one of the following rollup functions,
are optimized via partial result caching:

- sum_over_time()
- count_over_time()
- avg_over_time()
- increase()
- rate()

The basic idea of optimization is to calculate

  rf(m[d] @ t)

as

  rf(m[offset] @ t) + rf(m[d] @ (t-offset)) - rf(m[offset] @ (t-d))

where rf(m[d] @ (t-offset)) is cached query result, which was calculated previously

The offset may be in the range of up to 1 hour.

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.
