lib/pushmetrics: wait until the background goroutines, which push metrics, are stopped at pushmetrics.Stop()
Previously the was a race condition when the background goroutine still could try collecting metrics
from already stopped resources after returning from pushmetrics.Stop().
Now the pushmetrics.Stop() waits until the background goroutine is stopped before returning.

This is a follow-up for https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5549
and the commit fe2d9f6646 .

The support for this format will be added later.

lib/protoparser/opentelemetry: allow ingesting metrics without resource labels
Some clients may ingest samples via OpenTelemetry protocol without Resource labels.
Previously VictoriaMetrics was silently dropping such samples.

The commit 317834f876 added vm_protoparser_rows_dropped_total{type="opentelemetry",reason="resource_not_set"}
counter for tracking of such dropped samples. See https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5459

It is better from usability PoV to accept such samples instead of dropping them and incrementing the corresponding counter.

lib/promscrape: show -promscrape.cluster.memberNum values for vmagent instances, which scrape the given dropped target at /service-discovery page
The /service-discovery page contains the list of all the discovered targets
after the commit 487f6380d0 on all the vmagent instances
in cluster mode ( https://docs.victoriametrics.com/vmagent.html#scraping-big-number-of-targets ).

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.

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

lib/backup: consistently use path.Join() when constructing paths for s3, gs and azblob
E.g. replace `fs.Dir + filePath` with `path.Join(fs.Dir, filePath)`

The fs.Dir is guaranteed to end with slash - see Init() functions.
The filePath may start with slash. If it starts with slash, then `fs.Dir + filePath` constructs
an incorrect path with double slashes.
path.Join() properly substitutes duplicate slashes with a single slash in this case.

While at it, also substitute incorrect usage of filepath.Join() with path.Join()
for constructing paths to object storage systems, which expect forward slashes in paths.
filepath.Join() substittues forward slashes with backslashes on Windows, so this may break
creating or managing backups from Windows.

Show also the reason why every target is dropped at /service-discovery page.
This should improve debuging why particular targets are dropped.

While at it, do not remove dropped targets from the list at /service-discovery page
until the total number of targets exceeds the limit passed to -promscrape.maxDroppedTargets .
Previously the list was cleaned up every 10 minutes from the entries, which weren't updated
for the last minute. This could complicate debugging of dropped targets.

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.
