0451a1c9e0 app/vlinsert: follow-up for 37ed1842ab
- Properly decode protobuf-encoded Loki request if it has no Content-Encoding header.
  Protobuf Loki message is snappy-encoded by default, so snappy decoding must be used
  when Content-Encoding header is missing.

- Return back the previous signatures of parseJSONRequest and parseProtobufRequest functions.
  This eliminates the churn in tests for these functions. This also fixes broken
  benchmarks BenchmarkParseJSONRequest and BenchmarkParseProtobufRequest, which consume
  the whole request body on the first iteration and do nothing on subsequent iterations.

- Put the CHANGELOG entries into correct places, since they were incorrectly put into already released
  versions of VictoriaMetrics and VictoriaLogs.

- Add support for reading zstd-compressed data ingestion requests into the remaining protocols
  at VictoriaLogs and VictoriaMetrics.

- Remove the `encoding` arg from PutUncompressedReader() - it has enough information about
  the passed reader arg in order to properly deal with it.

- Add ReadUncompressedData to lib/protoparser/common for reading uncompressed data from the reader until EOF.
  This allows removing repeated code across request-based protocol parsers without streaming mode.

- Consistently limit data ingestion request sizes, which can be read by ReadUncompressedData function.
  Previously this wasn't the case for all the supported protocols.

71bb9fc0d0 app/vminsert: properly apply relabeling at ingestion
Regression was introduced at 564e6ea024
after implementing:
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6928

ctx.Labels array could be incorrectly updated and changes to it after
relabeling rules can be lost.
E.g. ctx.Labels passed to WriteDataPoint function as slice copy, but
results of relabeling only changed an actual slice at ctx.Labels.

This commit replaces implicit relabeling call with explicit
`TryPrepareLabels` function.
It also reduces code diffs with cluster version and adds integration tests

564e6ea024 app/{vminsert,vmagent}: drop time series on exceeding labels limits.
Previously, time series with labels exceeding the configured limits were truncated and written to storage, potentially causing data inconsistency. This could lead to collisions between time series and make it difficult to identify the source due to truncated labels.

This commit changes the behavior:
*  Such time series are now rejected outright.
* Rejected time series are logged to stdout, and corresponding counters are incremented.  
* removes `vm_too_long_label_values_total`, `vm_too_long_label_names_total`, `vm_metrics_with_dropped_labels_total` metrics.  
* adds new values `[too_many_labels,too_long_label_name,too_long_label_value]`  to `reason` label of the `vm_rows_ignored_total` metric name

0160435802 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

c63755c316 lib/writeconcurrencylimiter: improve the logic behind -maxConcurrentInserts limit
Previously the -maxConcurrentInserts was limiting the number of established client connections,
which write data to VictoriaMetrics. Some of these connections could be idle.
Such connections do not consume big amounts of CPU and RAM, so there is a little sense in limiting
the number of such connections. So now the -maxConcurrentInserts command-line option
limits the number of concurrently executed insert requests, not including idle connections.

It is recommended removing -maxConcurrentInserts command-line option, since the default value
for this option should work good for most cases.

dc9eafcd02 app/{vminsert,vmagent}: add -sortLabels command-line option for sorting time series labels before ingesting them in the storage
This option can be useful when samples for the same time series are ingested with distinct order of labels.
For example, metric{k1="v1",k2="v2"} and metric{k2="v2",k1="v1"}.
