The new version of github.com/VictoriaMetrics/metricsql handles $__interval and $__rate_interval
inside rollup functions in more correct way - it drops square brakets, so VictoriaMetrics
could automatically detect the needed lookbehind window depending on the time distance between real samples.
For example, rate(m[$__rate_interval]) is parsed and processed as rate(m) now.
Make sure that the maximum log field name, which can be generated by JSONParser.ParseLogMessage,
doesn't exceed the hardcoded limit maxFieldNameSize. Stop flattening of nested JSON objects
when the resulting field name becomes longer than maxFieldNameSize, and return the nested JSON object
as a string instead.
This should prevent from parse errors when ingesting deeply nested JSON logs with long field names.
- `contains_any` selects logs with fields containing at least one word/phrase from the provided list.
The provided list can be generated by a subquery.
- `contains_all` selects logs with fields containing all the words and phrases from the provided list.
The provided list can be generated by a subquery.

### Describe Your Changes
> (currently in DRAFT) This dashboard and the docs may look differently
after recent review and the feedback received.
As requested by our customers, this PR introduces `anomaly score`-based
dashboard for `vmanomaly` to improve the visual experience and ease the
drill down debugging process for respective anomaly detection setups.
Accompanying guide (under `default` preset mode) is provided as well.
- [For additional
benefits](https://docs.victoriametrics.com/victoriametrics-datasource/#motivation),
the dashboard is based on [VictoriaMetrics
datasource](https://docs.victoriametrics.com/victoriametrics-datasource/)
rather than on `Prometheus` datasource
- Tested locally and on our https://play.victoriametrics.com/
`anomaly_score` data (tenant ID 0)
- To check the guide, build the docs locally (`vmdocs`, `make run
local`) and follow to the
http://localhost:1313/anomaly-detection/presets/#default section

Previously if rule group parameters were changed, alerting rules related metrics could be deleted due to bug at `utils/metrics` package.
This commit introduces `metrics.Set` per rule group. It holds group and alerting rules metrics. It properly unregister alerting rules metrics and addresses issue.
In addition:
- expose group metrics only once group is started - this helps to avoid
exposing metrics for groups which are created during YAML unmarshaling
and only used to update existing group.
- properly close rules which are discarded after updating existing rules
so that metrics are also correctly closed.
- detect file renames and properly recreate groups "moved" between files.

Examples:
- `top 5 x, y` is equivalent to `top 5 by (x, y)`
- `uniq foo, bar` is equivalent to `uniq by (foo, bar)`
- `unroll foo, bar` is equivalent to `unroll (foo, bar)`
_time:<=max_time filter must include logs with timestamps matching max_time.
For example, _time:<=2025-02-24Z must include logs with timestamps until the end of February 24, 2025.
Examples:
_time:>=2025-02-24Z selects logs with timestamps bigger or equal to 2025-02-24 UTC
_time:>1d selects logs with timestamps older than one day comparing to the current time
This simplifies writing queries with _time filters.

It looks like the version deployed works differently than in local, and
some paths are not taken correctly. This commit fixes that by adding
absolute paths to the 2 images included in this section.

Currently, vmalert uses a fixed 10-second client timeout for notifiers,
which can prevent large sets of alerts from being sent successfully.
This introduces `-notifier.sendTimeout` flag to vmalert to control the
client timeout duration for the notifiers.

Inside PARAM-VALUE, the characters '"' (ABNF %d34), '\' (ABNF %d92),
and ']' (ABNF %d93) MUST be escaped. This is necessary to avoid
parsing errors. Escaping ']' would not strictly be necessary but is
REQUIRED by this specification to avoid syslog application
implementation errors. Each of these three characters MUST be
escaped as '\"', '\\', and '\]' respectively. The backslash is used
for control character escaping for consistency with its use for
escaping in other parts of the syslog message as well as in traditional syslog.

Use `rate_sum` instead of `total` output for the following reasons:
* `rate_sum` is far less sensitive for data delays than `total`, since
it represents the speed of change instead of absolute values.
* `rate_sum` remove need in using `rate` function for calculating final
results on query time.
