Previously Block columns wasn't properly limited by maxColumnsPerBlock.
And it was possible a case, when more columns per block added than
expected.
For example, if ingested log stream has many unuqie fields
and it's sum exceed maxColumnsPerBlock.
We only enforce fieldsPerBlock limit during row parsing, which limits
isn't enough to mitigate this issue. Also it
would be very expensive to apply maxColumnsPerBlock limit during
ingestion, since it requires to track all possible field tags
combinations.
This commit adds check for maxColumnsPerBlock limit during
MustInitFromRows function call. And it returns offset of the rows and
timestamps added to the block.
Function caller must create another block and ingest remaining rows
into it.

This metric tracks an approximate amounts of bytes processed when parsing the ingested logs.
The metric is exposed individually per every supported data ingestion protocol. The protocol name
is exposed via "type" label in order to be consistent with vl_rows_ingested_total metric.
Thanks to @tenmozes for the initial idea and implementation at https://github.com/VictoriaMetrics/VictoriaMetrics/pull/7682
While at it, remove the unneeded "format" label from vl_rows_ingested_total metric.
The "type" label must be enough for encoding the data ingestion format.
### Describe Your Changes
- Fixes the handling of the `showLegend` flag.
- Fixes the handling of `alias`.
- Adds support for alias templates, allowing dynamic substitutions like
`{{label_name}}`.

### Describe Your Changes
- **Memory Optimization**: Reduced memory consumption on the "Group" and
"JSON" tabs by approximately 30%.
- **Table Pagination**: Added pagination to the "Table" view with an
option to select the number of rows displayed (from 10 to 1000 items per
page, with a default of 1000). This change significantly reduced memory
usage by approximately 75%.

Previously, when the alert got resolved shortly before the vmalert
process shuts down, this could result in false alerts.
This change switches vmalert to use MetricsQL function during alerts state restore, which makes it
incompatible for state restoration with PromQL.

- The --delete option is needed to be passed to rsync during backups,
Since otherwise the backup may contain superfluous files after the second run of rsync,
because these files can be already removed at the source because of background merge
- the --delete option is needed when restoring from backup in order to remove superfluous files
from the destination directory. Otherwise these files may lead to inconsistent data at VictoriaLogs.
By default the delay equals to 1 second.
While at it, document refresh_interval query arg at /select/logsql/tail endpoint.
Thanks to @Fusl for the idea and the initial implementation at https://github.com/VictoriaMetrics/VictoriaMetrics/pull/7428
### Describe Your Changes
add sorting of logs by groups and within each group by time in desc
order. See #7184 and #7045

Loki protocol supports optional `metadata` object for each ingested line. It's added as 3rd field at the (ts,msg,metadata) tuple. Previously, loki request json parsers rejected log line if tuple size != 2.
This commit allows optional tuple field. It parses it as json object and adds it as log metadata fields to the log message stream.

User experience suggests that examples shouldn't have `-rule.defaultRuleType=vlogs` set,
as it may confuse users who run vmalert with their existing rules or only use
rules from examples for testing purposes.
This change is supposed to remove the confusion by removing `-rule.defaultRuleType=vlogs`
from default recommendations and explcitily specifying `type` on group level in examples.

This commit adds the following changes:
- Added support to push datadog logs with examples of how to ingest data
using Vector and Fluentbit
- Updated VictoriaLogs examples directory structure to have single
container image for victorialogs, agent (fluentbit, vector, etc) but
