lib/{mergeset,storage}: perform at most one assisted merge per each call to addRows/addItems
This should reduce tail latency during data ingestion.

This shouldn't slow down data ingestion in the worst case, since assisted merges are spread among
distinct addRows/addItems calls after this change.

lib/logstorage/datadb: remove parts merge cond (#4828)
It was added in order to limit number of goroutines performing assisted merges during ingestion.
It turned out that blocking ingestion goroutines lower ingestion performance and limits overall ingestion around 40k items per seconds because of lock contention.
Removing parts merge sync.Cond allows to remove lock contention at write path and significantly improves write performance.

lib/promscrape/discovery/kubernetes: supress context.Cancelled error in logs (#5048)
lib/promscrape/discovery/kubernetes: supress context.Cancelled error in logs

It is possible that context.Cancelled will appear after k8s watcher was closed due to reload(see https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4850).

Logging an error misinforms user and looks like vmagent discovery will stop working even though this does not affect discovery.

lib/promscrape/discovery/kubernetes: wait for 10 seconds before checking whether the urlWatcher must be stopped
This should prevent from excess urlWatcher churn on config reload, since it leads to removal of all the apiWatchers
before creating new apiWatchers. So, every config reload would lead to stopping of all the previous urlWatchers
and starting new urlWatchers.

The new logic gives 10 seconds for config reload before stopping unused urlWatchers.

lib/promscrape/client: sync timeout for HostClient and http.Client (#4889)
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.

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.

- 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 .

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
