Split unique values (groups) into shards according to the configured concurrency
during processing of the matching rows if the number of unique values exceeds the hardcoded threshold.
Previously this splitting was performed unconditionally at the merge stage when merging independently
calculated per-CPU states into a single state. It is faster to perform the split during rows processing
if the number of unique values is big.
This gives up to 30% perfromance improvements when these pipes are applied to big number of unique values (groups).
The number of worker shards per each pipe processor is created during query initialization.
This number equals to the `options(concurrency=N)` if this option is set or to the number of available CPU cores.
This means that all the pipes must adhere the given concurrency when passing data blocks
to the next pipe.
See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/8201
The bug has been introduced in 0214aa328e
vmauth uses 'lib/httpserver' for serving HTTP requests. This server
unconditionally defines built-in routes (such as '/metrics',
'/health', etc). It makes impossible to proxy `HTTP` requests to backends with the same routes.
Since vmauth's httpserver matches built-in route and return local
response.
This commit adds new flag `httpInternalListenAddr` with
default empty value. Which removes internal API routes from public
router and exposes it at separate http server.
For example given configuration disables private routes at `0.0.0.0:8427` address and serves it at `0.0.0.0:8426`:
`./bin/vmauth --auth.config=config.yaml --httpListenAddr=:8427 --httpInternalListenAddr=127.0.0.1:8426`

This commit improves integration with third-party solutions who rely on non-root
endpoints (i.e. MinIO) when the vmselect path has been specified in the
configured Prometheus URL like:
`http://vmselect.:8481/select/0/prometheus`
Comparable change has been done before
(b885a3b6e9), however only takes care of
the root path. This means endpoints `-/healthy` and `-/ready` are still
not available on full vmselect Prometheus paths, resulting in
unsupported path requests.
This change makes these endpoints available on the full paths like:
`/select/0/prometheus/-/healthy` and `/select/0/prometheus/-/ready`,
thus achieving full Prometheus compatibility for external dependencies.

### Describe Your Changes
The cardinality limiter in this case does not receive the actual
metricID but some other value found in r.TSID.MetricID and is not
initialized. Depending on the system and/or go runtime implementation,
this value can be 0 or some garbage value (which shouldn't have too wide
a range). Thus, there basically no limit for inserted metricIDs.

At this time `bufferedwriter` [silently ignores connection close
errors](78eaa056c0/lib/bufferedwriter/bufferedwriter.go (L67)).
It may be very convenient in some situations (to not log such
unimportant errors), but it's too implicit and unsafe for the others.
For example, if you close [export
API](https://docs.victoriametrics.com/#how-to-export-time-series) client
connection in the middle of communication, VictoriaMetrics won't notice
it and will start to hog CPU by exporting all the data into nowhere
until it process all of them. If you'll make a few retries, it will be
effectively a DoS on the server.
This commit replaces this implicit error suppressing with explicit error
handling which fixes the issue with export API.

1. Metric name
2. **Copy _stream name** - copies the full stream name in the format
`{field1="value1", ..., fieldN="valueN"}`.
3. **Add _stream to filter** - adds the full stream value to the current
filter:
`_stream: {field1="value1", ..., fieldN="valueN"} AND (old_expr)`.
4. **Exclude _stream from filter** - excludes the stream from the
current filter:
`(NOT _stream: {field1="value1", ..., fieldN="valueN"}) AND (old_expr)`.
5. List of fields with options:
- Copy as `field: "value"`.
- Add to filter: `field: "value" AND (old_expr)`.
- Exclude from filter: `-field: "value" AND (old_expr)`.
6. Total number of hits for the stream.

The purpose of extra filters ( https://docs.victoriametrics.com/victorialogs/querying/#extra-filters )
is to limit the subset of logs, which can be queried. For example, it is expected that all the queries
with `extra_filters={tenant=123}` can access only logs, which contain `123` value for the `tenant` field.
Previously this wasn't the case, since the provided extra filters weren't applied to subqueries.
For example, the following query could be used to select all the logs outside `tenant=123`, for any `extra_filters` arg:
* | union({tenant!=123})
This commit fixes this by propagating extra filters to all the subqueries.
While at it, this commit also properly propagates [start, end] time range filter from HTTP querying APIs
into all the subqueries, since this is what most users expect. This behaviour can be overriden on per-subquery
basis with the `options(ignore_global_time_filter=true)` option - see https://docs.victoriametrics.com/victorialogs/logsql/#query-options
Also properly apply apply optimizations across all the subqueries. Previously the optimizations at Query.optimize()
function were applied only to the top-level query.
logger.Fatalf("BUG: ...") complicates investigating the bug, since it doesn't show the call stack,
which led to the bug. So it is better to consistently use logger.Panicf("BUG: ...") for logging programming bugs.
Previously, NewChild elements of querytracer could be referenced by concurrent
storageNode goroutines. After earlier return ( if search.skipSlowReplicas is set), it is
possible, that tracer objects could be still in-use by concurrent workers.
It may cause panics and data races. Most probable case is when parent tracer is finished, but children
still could write data to itself via Donef() method. It triggers read-write data race at trace
formatting.
This commit adds a new methods to the querytracer package, that allows to
create children not referenced by parent and add it to the parent later.
Orphaned child must be registered at the parent, when goroutine returns. It's done synchronously by the single caller via finishQueryTracer call.
If child didn't finished work and reference for it is used by concurrent goroutine, new child must be created instead with
context message.
It prevents panics and possible data races.

This is done via 'options(concurrency=N)' prefix for the query.
For example, the following query is executed on at most 4 CPU cores:
options(concurrency=4) _time:1d | count_uniq(user_id)
This allows reducing RAM and CPU usage at the cost of longer query execution times,
since by default every query is executed in parallel on all the available CPU cores.
See https://docs.victoriametrics.com/victorialogs/logsql/#query-options
Also always initialize Query.timestamp with the timestamp from the lexer.
This should avoid potential problems with relative timestamps inside inner queries.
For example, the `_time:1h` filter in the following query is correctly executed
relative to the current timestamp:
foo:in(_time:1h | keep foo)

`doInternal` has adaptive staleness detection mechanism. It is
calculated using timestamp distance between samples in selected list of
samples. It is dynamic because VM can store signals from many sources
with different samples resolution. And while it works for most of cases,
there are edge cases for rollup functions that are comparing values
between windows: increase, increase_pure, delta.
The edge case 1.
There was a gap between series because of the missed scrape or two. In
this case staleness will trigger and increase-like functions will assume
the value they need to compare with is 0. In result, this could produce
spikes for a flappy data - see
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/894 This
problem was solved by introducing a `realPrevValue` field -
1f19c167a4.
It stores the closest real sample value on selected interval and is used
for comparison when samples start after the gap.
The edge case 2.
`realPrevValue` doesn't respect staleness interval. In result, even if
gap between samples is huge (hours), the increase-like functions will
not consider it as a new series that started from 0. See
https://github.com/VictoriaMetrics/VictoriaMetrics/pull/8002.
Covering both edge cases is tricky, because `realPrevValue` has to
respect and not respect the staleness interval in the same time. In
other words, it should be able to ignore periodic missing gaps, but
reset if the gap is too big. While "too big gap" can't be figured out
empirically, I suggest using `-search.maxStalenessInterval` for this
purpose. If `-search.maxStalenessInterval` is set to 0 (default), then
`realPrevValue` ignores staleness interval. If
`-search.maxStalenessInterval` is > 0, then `realPrevValue` respects it
as a staleness interval.

Commit eef6943084 added new test
functions. Which checks various cases for metricName registration at
data ingestion.
Initial dataset size had 4 batches with 100 rows each. It works fine at
machines with 5GB+ memory.
But i386 architecture supports only 4GB of memory per process.
Due to given limitations, batch size should be reduced to 3 batches and
30 rows. It keeps the same
test funtionality, but reduces overall memory usage to ~3GB.

Samples parsing is a hot path. Bad client could easily overwhelm
receiver with bad or unsupported data. So it is better to throttle such
messages.
