After changes at commit 787b9cd. Minimal timestamps for extDB check was performed without context of the index search prefix.
It worked fine for Single node version, but for cluster version a different prefix was used for
metricID search requests. It may lead to incomplete results, if minimal missing timestamp was cached
for the tenant with different ingestion patterns.
Minimal reproducible case is:
- metrics were ingested for tenants 0 and 1
- at some point in time metrics ingestion for tenant 1 stopped
- index records have the following timestamps layout:
tenant 0: 1,2,3,4,5,6
tenant 1: 1,2,3,4
- after indexDB rotation, containsTimeRange lookups may produce
incorrect results:
time range request for tenant 1 - 5:6 caches 5 as min timestamp
request for the same or smaller time range for tenant 0 now returns
empty results.
Second case:
- requests for the tenant without metrics always updates atomic value with incorrect minimal time range for other tenants.
This commit replaces single atomic with map of search prefix keys. It should have slight performance overhead,
but work consistently for cluster version. minMissingTimestamp is cached by prefix search key, which included tenantID.
Since it will be only populated at runtime, it doesn't hold unused tenants for queries.

This commit fixes panic for multitenant requests and empty storage node responses for tenants api.
It also optimizes `populateSqTenantTokensIfNeeded` function calls, by making it only once for query request. Previously it was incorrectly called multiple times per each storage node request.

This commit makes vmauth respect the routing config for unauthorized
requests for requests that despite having Authorization header failed to
authorize successfully.
It covers the following use-cases:
- vmauth is used at load-balanacer and must forward requests as is. There is no any authorization configs.
- vmauth has authorization config, but it must forward requests with invalid credential tokens to some other backend.

- 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.

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.

Previously vmgateway returned error for the requests with multitenant
tenant.
This commit allows to rate limit multitenant requests and apply global

Currently it supports only queries for rate limiting.

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.
