Numeric fields can be stored as const values in the block of logs. In this case the `sort` pipe
was incorrectly comparing such values as strings instead of numbers. This results in incorrect
sort results. For example, 123 was smaller than 2. Fix this by removing the incorrect case
for comparing const fields.
While at it, replace lessString() with strings.LessNatural() in the sortBlockLess.
This improves sorting performance a bit, since the sortBlockLess function already tried
comparing numeric values, and it doesn't need to spend CPU time on such a comparison again inside lessString() call.
The commit 42c9183281 wasn't correct by replacing strings.LessNatural() with lessString()
inside the sortBlockLess() function.
* simplify wording
* update styles
* remove extra info about go application details. The details are likely
not needed and we didn't have details for rolling-dice app anyway. So
keep it simple for consstency and brevity.
* update navigation for simplicity sake
* fix typos

vmauth started to use request.Host after commit
f4776fec1b for`src_hosts` routing rules.
This commit adds http.Request.Host to the debugInfo output in order to
be consistent with routing logic.

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

While at at, allow passing an array of string values per each JSON entry at extra_filters and extra_stream_filters.
For example, `extra_filters={"foo":["bar","baz"]}` is converted into `foo:in("bar", "baz")` extra filter,
while `extra_stream_fitlers={"foo":["bar","baz"]}` is converted into `{foo=~"bar|baz"}` extra filter.
This should simplify creating faceted search when multiple values per a single log field must be selected.

Such log fields do not give any useful information during logs' exploration.
They just clutter the output of the `facets` pipe. So it is better to drop such fields by default.
If these fields are needed, then `keep_const_fields` option can be added to `facets` pipe.

- Remove Loki sink, since it brings more troubles when users try using it in Vector.
For example, it encodes all the log fields as a JSON string and puts it into "message" field.
This results in storing the "message" field with the JSON string containing all the log fields
in VictoriaLogs. This is not what expected - every log field must be stored as a separate field
according to https://docs.victoriametrics.com/victorialogs/keyconcepts/
- Remove 'mode: bulk' option from Elasticsearch sink configuration, since this option is set by default to this value,
so there is no need in explicit setting.
- Add 'compression: gzip' to all the config examples, since the compression reduces the used network bandwidth by 4-5 times,
while it doesn't increase CPU usage too much at both Vector and VictoriaLogs sides. So it is better to enable the compression in config examples.
- Mention about HTTP parameters accepted by VictoriaLogs data ingestion APIs in both examples for Elasticsearch and JSON line protocols.
### Describe Your Changes
This PR fixes#5796. See the points 6 and 7 in `Steps to reproduce`:
> Now let's set time to only 5ms past the timestamp of the first point,
since even 199ms worked for the second point. Surprise, the point isn't
returned 💥:
>
> ```curl -s $VMQURL -d 'query=series1' -d 'time=1707123456705' -d
'step=1ms' | grep 10 # nothing!```
>
> But, 4ms works: 🤨🤔
>
> ```curl -s $VMQURL -d 'query=series1' -d 'time=1707123456704' -d
'step=1ms' | grep 10 # found```
This happens so because the actual step becomes 5ms due to jitter being
applied. THe fix is to do not apply jitter if scrape interval was not
detected (the case when vmstorage returns only one result). In this case
the scrape interval is set to `5m+step`.
An integration test has been added to check the steps to reproduce and
then to confirm that fix works. Note that the cluster tests are
currently disabled because the fix is not in cluster branch yet.

Previously cluster with the following vmselect configuration:
./bin/vmselect
-storageNode=gr1/:8211,gr1/:8212
-storageNode=gr2/:8213,gr2/:8214
-search.skipSlowReplicas=true
-globalReplicationFactor=2
Here we have two vmstorage groups and -globalReplicationFactor=2, which effectively means that "every ingested sample is replicated across multiple vmstorage groups". Hence, gr1 and gr2 contain identical data set. And when we set -search.skipSlowReplicas=true it is expected vmselect should return result as soon as at least one storage group returned the full result.
In current state, -search.skipSlowReplicas is ignored on the storage group level. It is only respected within the group (with -replicationFactor flag).
This commit fixes global replication for skipSlowReplicas.
To ensure that the fix works and does not break
anything replication tests have been added. For checking the fix for
skipping slow replicas see `testGroupSkipSlowReplicas()`.
To emulate storage groups, the integration test creates a cluster with
multilevel vminsert. The L1 inserts are group-level inserts, each writes
to its own group of vmstorages. The L2 vminsert is a global vminsert
that writes replicated to the L1 vminserts.
To enable multilevel inserts changes in apptest framework and
`lib/ingestserver/clusternative/server.go` were necessary.

Previously service labels won't be attached when `role: tasks` is set.
Because the `addServicesLabels` function is shared by `role: tasks` and
`role: services`, and it will return nothing when `vip.Addr` is invalid
or empty.
In Prometheus, even if `vip.Addr` is empty, it attach common service
labels with [a standalone
function](f10c3454e9/discovery/moby/services.go (L129)),
which offers:
- `__meta_dockerswarm_service_id`: the id of the service.
- `__meta_dockerswarm_service_name`: the name of the service.
- `__meta_dockerswarm_service_mode`: the mode of the service.
- `__meta_dockerswarm_service_label_<labelname>`: each label of the
service, with any unsupported characters converted to an underscore.
This PR add a `addServicesLabelsForTask`, to replace the usage of
`addServicesLabels` when `role: tasks` is set. This function offers
common service labels listed above.

Previously after configuration reload call `externalURL` templaing function defined at external templates could be lost. Since it was added only at initial `Load` call and never copied during template reload process.
External templates for vmalert could be defined via `-rule.templates` flag.
This commit properly reload external templates. It's no longer copies mutated templates and instead fully reloads it each time if there is any changes.
Previously, during de-duplication staleness markers could be removed due to incorrect logic at
values equality check.
During the evaluation of read query vmselect deduplicates samples using dedupInterval option. It picks the highest value across all points with the same timestamp next to the border of dedupInterval. The issue is any comparison with NaN via <, > returns false. This means that the position of NaN in srcValues could affect the result.
This commit changes this logic with additional step, that explicitly checks for staleness marker for the following cases:
1. Deduplication on vmselect
2. Deduplication in vmstorage during merges
3. Deduplication in stream aggregation
check performed only for stale markers, because other NaNs are rejected on ingestion
by vmstorage or by stream aggregation.
Checking for stale markers in general slows down dedup speed by 3%:
