### Describe Your Changes
Fix Date metricid cache consistency under concurrent use.
When one goroutine calls Has() and does not find the cache entry in the
immutable map it will acquire a lock and check the mutable map. And it
is possible that before that lock is acquired, the entry is moved from
the mutable map to the immutable map by another goroutine causing a
cache miss.
The fix is to check the immutable map again once the lock is acquired.

This reverts commit 5ecf439078.
Reason for revert: the previous logic was correct.
The purpose of `-search.maxSamplesPerQuery` command-line flag is to limit the amounts of CPU resources,
which could be taken by a single query - see https://docs.victoriametrics.com/#resource-usage-limits .
VictoriaMetrics processes samples in blocks during querying - it reads the block, then unpacks it,
then filters out samples outside the selected time range. This means that it _spends CPU time_
on reading and unpacking of _all the samples_ in every block on the requested time range,
even if only a single sample per each block matches the given time range.
The previous logic was effectively limiting CPU time a single query could take.
The new logic fails limiting CPU time a single query could take in some pathological cases
when only a small fraction of samples per each requested block fit the requested time range.
This allows performing multiplication DoS-attacks by querying very narrow time ranges over historical blocks,
which tend to be full. For example, if the `-search.maxSamplesPerQuery` equals to a billion,
and the query requests a single sample out of 8K samples per each block, this means that the query
may unpack a billion of such blocks without exceeding the limit, e.g. it may unpack and process 8K*1e9=8e12 samples.
This is not what the resource usage limits were created for originally - see https://docs.victoriametrics.com/#resource-usage-limits
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5851
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6464
Reason for revert: this commit doesn't resolve real security issues,
while it complicates the resulting code in subtle ways (aka security circus).
Comparison of two strings (passwords, auth keys) takes a few nanoseconds.
This comparison is performed in non-trivial http handler, which takes thousands
of nanoseconds, and the request handler timing is non-deterministic because of Go runtime,
Go GC and other concurrently executed goroutines. The request handler timing is even
more non-deterministic when the application is executed in shared environments
such as Kubernetes, where many other applications may run on the same host and use
shared resources of this host (CPU, RAM bandwidth, network bandwidth).
Additionally, it is expected that the passwords and auth keys are passed via TLS-encrypted connections.
Establishing TLS connections takes additional non-trivial time (millions of nanoseconds),
which depends on many factors such as network latency, network congestion, etc.
This makes impossible to conduct timing attack on passwords and auth keys in VictoriaMetrics components.

### Describe Your Changes
Trimming content which is loaded from an external pass leads to obscure
issues in case user-defined input contained trimmed chars. For example.
user-defined password "foo\n" will become "foo" while user will expect
it to contain a new line.
---
For example, a user defines a password which ends with `\n`. This often
happens when user Kubernetes secrets and manually encodes value as
base64-encoded string.
In this case vmauth configuration might look like:
```
users:
- url_prefix:
- http://vminsert:8480/insert/0/prometheus/api/v1/write
name: foo
username: foo
password: "foobar\n"
```
vmagent configuration for this setup will use the following flags:
```
-remoteWrite.url=http://vmauth:8427/
-remoteWrite.basicAuth.passwordFile=/tmp/vmagent-password
-remoteWrite.basicAuth.username="foo"
```
Where `/tmp/vmagent-password` is a file with `foobar\n` password.
Before this change such configuration will result in `401 Unauthorized`
response received by vmagent since after file content will become
`foobar`.
---
An example with Kubernetes operator which uses a secret to reference the
same password in multiple configurations.
<details>
<summary>See full manifests</summary>
`Secret`:
```
apiVersion: v1
data:
name: Zm9v # foo
password: Zm9vYmFy # foobar\n
username: Zm9v= # foo
kind: Secret
metadata:
name: vmuser
```
`VMUser`:
```
apiVersion: operator.victoriametrics.com/v1beta1
kind: VMUser
metadata:
name: vmagents
spec:
generatePassword: false
name: vmagents
targetRefs:
- crd:
kind: VMAgent
name: some-other-agent
namespace: example
username: foo
# note - the secret above is referenced to provide password
passwordRef:
name: vmagent
key: password
```
`VMAgent`:
```
apiVersion: operator.victoriametrics.com/v1beta1
kind: VMAgent
metadata:
name: example
spec:
selectAllByDefault: true
scrapeInterval: 5s
replicaCount: 1
remoteWrite:
- url: "http://vmauth-vmauth-example:8427/api/v1/write"
# note - the secret above is referenced as well
basicAuth:
username:
name: vmagent
key: username
password:
name: vmagent
key: password
```
</details>
Since both config target exactly the same `Secret` object it is expected
to work, but apparently the result will be `401 Unauthrized` error.

- 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.

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.

The URL flag also allows loading its value from files if `file://`
