* check if `lastValue` was seen at least twice with different
timestamps. Otherwise, the difference between last timestamp and
previous timestamp could be `0` and will result into `NaN` calculation
* check if there items left in lastValue map after staleness cleanup.
Otherwise, `rate_avg` could have produce `NaN` result.

Signed-off-by: hagen1778 <roman@victoriametrics.com>
- Use bytesutil.InternString() instead of strings.Clone() for inputKey and outputKey in aggregatorpushSamples().
This should reduce string allocation rate, since strings can be re-used between aggrState flushes.
- Reduce memory allocations at dedupAggrShard by storing dedupAggrSample by value in the active series map.
- Remove duplicate call to bytesutil.InternBytes() at Deduplicator, since it is already called inside dedupAggr.pushSamples().
- Add missing string interning at rateAggrState.pushSamples().
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6402
The main change is getting rid of interning of sample key. It was
discovered that for cases with many unique time series aggregated by
vmagent interned keys could grow up to hundreds of millions of objects.
This has negative impact on the following aspects:
1. It slows down garbage collection cycles, as GC has to scan all inuse
objects periodically. The higher is the number of inuse objects, the
longer it takes/the more CPU it takes.
2. It slows down the hot path of samples aggregation where each key
needs to be looked up in the map first.
The change makes code more fragile, but suppose to provide performance
optimization for heavy-loaded vmagents with stream aggregation enabled.

### Describe Your Changes
Scratch based images will be using a separate tag: "(version)-scratch"
and will be built for the same architecture as regular images.
This is useful for environments with higher security standards. In this
case using alpine as base layer requires updating images more frequently
in order to get the latest updates for the base image, even in case the
user did not need to update VictoriaMetrics version.
Tested that scratch images work for:
- vmagent - enterprise with kafka and opensource
- cluster
- single-node
No issues observed so far.

This PR fixes an issue where parsing long `_msg` values caused errors,
resulting in some log records not being displayed.
The error occurred due to partial processing of strings. In some cases,
a long record could be split into multiple chunks, causing only part of
the record to be processed instead of the entire entry.

This should improve precision of `restarts` and `version change` annotations when
zooming-in/zooming-out on the dashboards.
The change also makes `restarts` dashboard visible on the panels, so user can disable it from
displaying if needed. This could be useful when restarts overlap with version change events.

Occasionally, vmagent sends empty blocks to downstream servers. If a
downstream server returns an unexpected response, vmagent gets stuck in
a retry loop. While vmagent handles 400 and 409 errors, there are
various prometheus remote write implementations that return different
error codes. For example, vector returns a 422 error. To mitigate the
risk of vmagent getting stuck in a retry loop, it is advisable to skip
sending empty blocks to downstream servers.
