lib/protoparser/openetelemetry: fixes panic (#4821)
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 (#4816)
* 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.

This leaded to invalid relabeling results such as one described here: https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4806

Moreover, value of `-dedup.minScrapeInterval` must be a multiple of vmalert's `evaluation_interval` in order to make sure that samples will be aligned between deduplication window periods.

vmctl: allow disabling binary export protocol (#4716)
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.

* wip

- 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.

vmalert: clarify docs for state restore with additional details
The important change is to highlight that restore procedure happens
only once and only for already loaded rules. Config hot-reload
doesn't trigger the restore procedure.

app/vmagent: add ability to shard outgoing data among multiple remote storage systems
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.

lib/streamaggr: follow-up for 736197179e
- 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 (#4652)
* 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.

app/vlinsert/loki: follow-up after 09df5b66fd
- Parse protobuf if Content-Type isn't set to `application/json` - this behavior is documented at https://grafana.com/docs/loki/latest/api/#push-log-entries-to-loki

- Properly handle gzip'ped JSON requests. The `gzip` header must be read from `Content-Encoding` instead of `Content-Type` header

- Properly flush all the parsed logs with the explicit call to vlstorage.MustAddRows() at the end of query handler

- Check JSON field types more strictly.

- Allow parsing Loki timestamp as floating-point number. Such a timestamp can be generated by some clients,
  which store timestamps in float64 instead of int64.

- Optimize parsing of Loki labels in Prometheus text exposition format.

- Simplify tests.

- Remove lib/slicesutil, since there are no more users for it.

- Update docs with missing info and fix various typos. For example, it should be enough to have `instance` and `job` labels
  as stream fields in most Loki setups.

- Allow empty of missing timestamps in the ingested logs.
  The current timestamp at VictoriaLogs side is then used for the ingested logs.
  This simplifies debugging and testing of the provided HTTP-based data ingestion APIs.

The remaining MAJOR issue, which needs to be addressed: victoria-logs binary size increased from 13MB to 22MB
after adding support for Loki data ingestion protocol at https://github.com/VictoriaMetrics/VictoriaMetrics/pull/4482 .
This is because of shitty protobuf dependencies. They must be replaced with another protobuf implementation
similar to the one used at lib/prompb or lib/prompbmarshal .

app/vmselect/promql: recommend to use (a op b) keep_metric_names instead of a op b keep_metric_names
The `a op b keep_metric_names` is ambigouos to `a op (b keep_metric_names)` when `b` is a transform or rollup function.
For example, `a + rate(b) keep_metric_names`. So it is better to use more clear syntax: `(a op b) keep_metric_names`

all: add support for or filters in series selectors
This commit adds ability to select series matching distinct filters via a single series selector.
For example, the following selector selects series with either {env="prod",job="a"}
or {env="dev",job="b"} labels:

  {env="prod",job="a" or env="dev",job="b"}

The `or` filter is supported in all the VictoriaMetrics tools now.

lib/storage: switch from global to per-day index for MetricName -> TSID mapping
Previously all the newly ingested time series were registered in global `MetricName -> TSID` index.
This index was used during data ingestion for locating the TSID (internal series id)
for the given canonical metric name (the canonical metric name consists of metric name plus all its labels sorted by label names).

The `MetricName -> TSID` index is stored on disk in order to make sure that the data
isn't lost on VictoriaMetrics restart or unclean shutdown.

The lookup in this index is relatively slow, since VictoriaMetrics needs to read the corresponding
data block from disk, unpack it, put the unpacked block into `indexdb/dataBlocks` cache,
and then search for the given `MetricName -> TSID` entry there. So VictoriaMetrics
uses in-memory cache for speeding up the lookup for active time series.
This cache is named `storage/tsid`. If this cache capacity is enough for all the currently ingested
active time series, then VictoriaMetrics works fast, since it doesn't need to read the data from disk.

VictoriaMetrics starts reading data from `MetricName -> TSID` on-disk index in the following cases:

- If `storage/tsid` cache capacity isn't enough for active time series.
  Then just increase available memory for VictoriaMetrics or reduce the number of active time series
  ingested into VictoriaMetrics.

- If new time series is ingested into VictoriaMetrics. In this case it cannot find
  the needed entry in the `storage/tsid` cache, so it needs to consult on-disk `MetricName -> TSID` index,
  since it doesn't know that the index has no the corresponding entry too.
  This is a typical event under high churn rate, when old time series are constantly substituted
  with new time series.

Reading the data from `MetricName -> TSID` index is slow, so inserts, which lead to reading this index,
are counted as slow inserts, and they can be monitored via `vm_slow_row_inserts_total` metric exposed by VictoriaMetrics.

Prior to this commit the `MetricName -> TSID` index was global, e.g. it contained entries sorted by `MetricName`
for all the time series ever ingested into VictoriaMetrics during the configured -retentionPeriod.
This index can become very large under high churn rate and long retention. VictoriaMetrics
caches data from this index in `indexdb/dataBlocks` in-memory cache for speeding up index lookups.
The `indexdb/dataBlocks` cache may occupy significant share of available memory for storing
recently accessed blocks at `MetricName -> TSID` index when searching for newly ingested time series.

This commit switches from global `MetricName -> TSID` index to per-day index. This allows significantly
reducing the amounts of data, which needs to be cached in `indexdb/dataBlocks`, since now VictoriaMetrics
consults only the index for the current day when new time series is ingested into it.

The downside of this change is increased indexdb size on disk for workloads without high churn rate,
e.g. with static time series, which do no change over time, since now VictoriaMetrics needs to store
identical `MetricName -> TSID` entries for static time series for every day.

This change removes an optimization for reducing CPU and disk IO spikes at indexdb rotation,
since it didn't work correctly - see https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1401 .

At the same time the change fixes the issue, which could result in lost access to time series,
which stop receving new samples during the first hour after indexdb rotation - see https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2698

The issue with the increased CPU and disk IO usage during indexdb rotation will be addressed
in a separate commit according to https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1401#issuecomment-1553488685
