- Document the change at docs/CHANGELOG.md
- Set the default value for -vmstorageUserTimeout to 3 seconds. This is much better
than the 0 value, which means that TCP connection to unreachable vmstorage could block
for up to 16 minutes.
- Document -vmstorageUserTimeout at docs/Cluster-VictoriaMetrics.md
Initially, stream parse mode was reading data from response and parsing it on flight. This was causing longer delay to read the whole response and required increasing timeout value to allow data processing while reading. So that 908e35affd increased timeout value to fix this.
But after 74c00a8762 response in stream parse mode is saved into memory and then parsed eliminating necessity of having timeout value higher that for usual scrape.

(cherry picked from commit 481a2c70fd)
Opentelemetry format allows histograms with non-counter buckets. In this case it makes no sense to add buckets into database
and save only counter with _count suffix.
It could be used as gauge.

* lib/promrelabel: fix relabeling if clause being applied to labels outside of current context
Relabeling is applied to each metric row separately, but in order to lower amount of memory allocations it is reusing labels.
Functions which are working on current metric row labels are supposed to use only current metric labels by using provided offset, but if clause matcher was using the whole labels set instead of local metrics.

Binary export API protocol can be disabled via `-vm-native-disable-binary-protocol` cmd-line flag when migrating data from VictoriaMetrics. Disabling binary protocol
can be useful for deduplication of the exported data before ingestion.
For this, deduplication need to be configured at `-vm-native-src-addr` side
and `-vm-native-disable-binary-protocol` should be set on vmctl side.

- Remove support for JSON parsing, since it is too fragile and is rarely used in practice.
The most clients send OpenTelemetry metrics in protobuf.
The JSON parser can be added in the future if needed.
- Remove unused code from lib/protoparser/opentelemetry/pb and lib/protoparser/opentelemetry/proto
- Do not re-use protobuf message between ParseStream() calls, since there is high chance
of high fragmentation of the re-used message because of too complex nested structure of the message.

Add -remoteWrite.shardByURL command-line flag, which instructs vmagent to spread evenly
outgoing time series data among the configured remote storage systems specified via -remoteWrite.url .
Samples for the same time series go to the same -remoteWrite.url . This allows building horizontally
scalable stream aggregation when samples for counter and histogram series must be aggregated
by the same second-level vmagent instance.
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4637
- Use a byte slice instead of a map for tracking indexes for matching series.
This improves performance, since access by slice index is faster than access by map key.
- Re-use the byte slice for tracking indexes for matching series.
This removes unnecessary memory allocations and improves stream aggregation performance a bit.
- Add an ability to return to the previous behvaiour by specifying -remoteWrite.streamAggr.dropInput command-line flag.
In this case all the input samples are dropped when stream aggregation is enabled.
- Backport the new stream aggregation behaviour from vmagent to single-node VictoriaMetrics when -streamAggr.config
option is set.
- Improve docs regarding this change at docs/CHANGELOG.md
- Document the new behavior at docs/stream-aggregation.md

* lib/storage: pre-create timeseries before indexDB rotation
during an hour before indexDB rotation start creating records at the next indexDB
it must improve performance during switch for the next indexDB and remove ingestion issues.
Since there is no need for creation new index records for timeseries already ingested into current indexDB
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4563
* lib/storage: further work on indexdb rotation optimization
- Document the change at docs/CHAGNELOG.md
- Move back various caches from indexDB to Storage. This makes the change less intrusive.
The dateMetricIDCache now takes into account indexDB generation, so it stores (date, metricID)
entries for both the current and the next indexDB.
- Consolidate the code responsible for idbNext pre-filling into prefillNextIndexDB() function.
This improves code readability and maintainability a bit.
- Rewrite and simplify the code responsible for calculating the next retention timestamp.
Add various tests for corner cases of this code.
- Remove indexdb pre-filling from RegisterMetricNames() function, since this function is rarely called.
It is OK to add indexdb entries on demand in this function. This simplifies the code.

- Hide `debug relabeling` column when -promscrape.dropOriginalLabels command-line flag is set
- Inline the code from the added template functions, since the code is harder to follow

Also, these functions are used only in one place, e.g. they do not reduce the amounts of code.
