`searchOptions` are always passed by ref, so there is no need to pass atomic.Uint64 by ref as well.

Use summaries in order to reduce cardinality generated by these metrics.
Also update label to include source of metric. Include request path for cases when it is guaranteed to be used by a single endpoint, use generic name in other cases ("search" - used by both "/query" and "/query_range", "search_metric_names" used by "/series" and graphite tag handlers).

Added metrics to track number of series read per individual query. Based on checking number of metricIDs fetched when performing search.

- Properly handle negative timestamps (e.g. timestamps before 1970-01-01)
- Optimize parsing floating-point timestamps by eliminating the memory allocation
needed for returning an error from strconv.ParseInt. Instead, check whether the string contains a dot,
and then parse it as a floating-point number.
- Add tests for ParseUnixTimestamp function.
- Make the code easier to understand and maintain by removing unneeded generic function toNano().

### Describe Your Changes
Add `vmalert_alerts_send_latency_seconds` metric for
alertmanager.notifier.
To measure the time for alertmanager calls to send alerts per notifier.
This is needed to see the latency for each notifier from vmalert calls.

### Fix scrapePool name
If in the scrape file, I do some magic and manipulate the job name then
Prometheus will show scrapePool as the original job name in the targets
API, but vmagent will set it to the final value which is wrong.
example
```
job: consul-targets
...
- source_labels: [ __meta_consul_service ]
regex: (\w+)[_-]exporter
target_label: job
replacement: $1
```
curl to prom API will show
`"scrapePool": "consul-targets",`
vmagent:
`""scrapePool": "node",`
before changes:
```
curl -s 'http://localhost:8429/api/v1/targets' | jq -r '.data.activeTargets[].scrapePool'| sort|uniq
blackbox
pgbackrest
postgres
```
after changes
```
curl -s 'http://localhost:8429/api/v1/targets' | jq -r '.data.activeTargets[].scrapePool'| sort|uniq
blackbox
consul-targets
```

Using zero interval for downsampling rules is not useful and caused a panic when performing validation of intervals.
Reject such rules during parsing in order to highlight incorrect usage and prevent panics.

(cherry picked from commit fd7b016c5b)
This feature allows to track query requests by metric names. Tracker
state is stored in-memory, capped by 1/100 of allocated memory to the
storage. If cap exceeds, tracker rejects any new items add and instead
registers query requests for already observed metric names.
This feature is disable by default and new flag:
`-storage.trackMetricNamesStats` enables it.
New API added to the select component:
* /api/v1/status/metric_names_stats - which returns a JSON
object
with usage statistics.
* /admin/api/v1/status/metric_names_stats/reset - which resets internal
state of the tracker and reset tsid/cache.
New metrics were added for this feature:
* vm_cache_size_bytes{type="storage/metricNamesUsageTracker"}
* vm_cache_size{type="storage/metricNamesUsageTracker"}
* vm_cache_size_max_bytes{type="storage/metricNamesUsageTracker"}

### Describe Your Changes
Previously, "selector @ another_selector" assumed that
"another_selector" metric is supposed to exist since "start" used in the
query.
If the query was evaluated in the following case (timestamps):
- start - 2, end - 10
- "another_selector" 5,6,7,8,9,10
- "selector" The resulting "at" timestamp would be taken from NaN (as
`int64(NaN * 1000)`), causing a panic or invalid behavior later.
Note that type cast of `NaN` to int64 is also platform-dependent, so
value of `int64(math.NaN() * 1000)` can produce `0` or max int64 on
different platforms and versions of Go.
This commit changes this and checks for the first non-NaN value. This
makes it easier to use for users as series are not always aligned and
returning an error in this case would disallow using this for some time
ranges.

Previously, opentelemetry attribute parsed added extra field names according to
golang JSON parser spec for structs:
```
struct AnyValue{
StringValue string
}
```
Was serialized into:
```
{"StringValue": "some-string"}
```
While opentelemetry-collector serializes it as
```
"some-string"
```
This commit changes this behaviour it makes parses compatible with opentelemetry-collector format. See test cases for examples.

### Describe Your Changes
Fix available from version hint. The feature was introduced in
[v1.91.0](https://docs.victoriametrics.com/changelog/changelog_2023/#v1910).
I noticed that the sentence uses both `{{% available_from "v1.91.0" %}}`
and a manual reference like `starting from
[v1.91](https://docs.victoriametrics.com/changelog/#v1910)`. Does {{%
available_from %}} fully supersede the manual changelog reference, and
should the later be removed? Or should\could both be used together?
