- 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

Previously, vmauth could have pick `buMin` as least loaded backend
without checking its status. In result, vmauth could have respond to the
user with an error even if there were healthy backends. That could
happen if healthy backends already had non-zero amount of concurrent
requests executing at the moment of least-loaded backend choosing logic.
Steps to reproduce:
1. Setup vmauth with two backends: healthy and non-healthy
2. Execute a bunch of concurrent requests against vmauth (i.e. Grafana
dash reload)
3. Observe that some requests will fail with message that all backends
are unavailable

Previously it incorrectly applied xFilesFactor, if it's value equal to 0.
This commit properly handles this case and returns result according to
the graphite documentation:
`xFilesFactor follows the same semantics as in Whisper storage schemas. Setting it to 0 (the default) means that only a single value in the series needs to be non-null for it to be considered non-empty, setting it to 1 means that all values in the series must be non-null. A setting of 0.5 means that at least half the values in the series must be non-null.`

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.

### Describe Your Changes
Fix https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7301
When querying with condition like `WHERE a=1` (looking for series A),
InfluxDB can return data with the tag `a=1` (series A) and data with the
tag `a=1,b=1` (series B).
However, series B is will be queried later and it's data should not be
combined into series A's data.
This PR filter those series that are not identical to the original query
condition.
For table `example`:
```
// time host region value
// ---- ---- ------ -----
// 2024-10-25T02:12:13.469720983Z serverA us_west 0.64
// 2024-10-25T02:12:21.832755213Z serverA us_west 0.75
// 2024-10-25T02:12:32.351876479Z serverA 0.88
// 2024-10-25T02:12:37.766320484Z serverA 0.95
```
The query for series A (`example_value{host="serverA"}`) and result will
be:
```SQL
SELECT * FROM example WHERE host = "serverA"
```
```json
{
"results": [{
"statement_id": 0,
"series": [{
"name": "cpu",
"columns": ["time", "host", "region", "value"],
"values": [
["2024-10-25T02:12:13.469720983Z", "serverA", "us_west", 0.64],
["2024-10-25T02:12:21.832755213Z", "serverA", "us_west", 0.75],
["2024-10-25T02:12:32.351876479Z", "serverA", null, 0.88],
["2024-10-25T02:12:37.766320484Z", "serverA", null, 0.95]
]
}]
}]
}
```
We need to abandon `values[0]` and `values[1]` because the value of
**unwanted** column `region` is not null.
As for series B (`example_value{host="serverA", region="us_west"}`), no
change needed since the query filter out unwanted rows already.
### Note
This is a draft PR for verifying the fix.

Previously vmgateway returned error for the requests with multitenant
tenant.
This commit allows to rate limit multitenant requests and apply global
rate limit for it.
Currently it supports only queries for rate limiting.
Related issue: https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7201
This commit also addresses gateway start-up crash if datasource.url is not accessible.
Previously vmgateway could crash at start-up with enabled rate limiting if datasource for metrics
was not avaiable for any reason. It seems, that crash is expected. But in fact it's not. For instance, datasource could be in restart phase.
Replaces crash with log message error. It increased availability of vmgateway component.

This commit adds `metric_relabel_configs` and `relabel_configs` fields
into the `global` section of scrape configuration file.
New fields are used as global relabeling rules for the scrape targets.
These relabel configs are prepended to the target relabel configs.
This feature is useful to:
* apply global rules to __meta labels from service discovery targets.
* drop noisy labels during scrapping.
* mutate labels without affecting metrics ingested via any of push
protocols.

In this case the _msg field is set to the value specified in the -defaultMsgValue command-line flag.
This should simplify first-time migration to VictoriaLogs from other systems.
- Remove leading whitespace from the first lines in 'HTTP parameters' chapter.
This whitespace isn't needed for the markdown formatting.
- Add leading whitespace for the second sentence in the list bullet describing AccountID and ProjectID HTTP headers.
This fixes markdown formatting for this list bullet.
This msy be useful when ingesting logs from different sources, which store the log message in different fields.
For example, `_msg_field=message,event.data,some_field` will get log message from the first non-empty field:
`message`, `event.data` and `some_field`.
If the number of output (bloom, values) shards is zero, then this may lead to panic
as shown at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7391 .
This panic may happen when parts with only constant fields with distinct values are merged into
output part with non-constant fields, which should be written to (bloom, values) shards.

"Single version" is unclear, since VM is also a single-executable. I
think "single-node" is clearer.
