Previously, this filter did not apply to virtual
machine scale sets, causing all virtual machines to be discovered.
This commit conditionally adds `resource_group` filter for Azure service discovery on virtual
machine scale sets.

https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7630.
doing similar changes for both vmagent and vminsert (like one in
https://github.com/VictoriaMetrics/VictoriaMetrics/pull/7399) ends up
with almost same implementations for each of packages instead of having
this shared code in one place. one of the reasons is the same Timeseries
and Labels structure from different prompb and prompbmarshal packages.
My proposal is to use structures from prompb package only to
marshal/unmarshal sent/received data, but for internal transformations
use only structures from prompbmarshal package
Another example, where it already can help to simplify code is streaming
aggregation pipeline for vmsingle (now it first marshals
prompb.Timeseries to storage.MetricRow and then if streaming aggregation
or deduplication is enabled it unmarshals all the series back but to
prompbmarshal.Timeseries)

Previously, default dial timeout was used for kubernetes API server connection.
This commit changes it for custom dialer used by the all VictoriaMetrics components. It has lower connection timeout (30s by default).

Previously multitenant cache was inited before flag.Parse call. It
didn't allow to change cache expiration value and default value was
always used.
This commit adds cache init at the first time cache was called.
Also this commit adds small cache improvements:
* chore for cleanup cache, it now uses common pattern for in-place items
filtering
* fail cache request fast if item is already expired

This is a follow-up after 3120dc2
- Consistently use key for rollupCache in multitenant mode cache keys use different authTokens. Previously it could lead to panic in rare cases when cache state was inconsistent.
- Do not share `err` variable across goroutines for `processBlock` function. It could lead to data races.

Previously, when the alert got resolved shortly before the vmalert
process shuts down, this could result in false alerts.
This change switches vmalert to use MetricsQL function during alerts state restore, which makes it
incompatible for state restoration with PromQL.

### Describe Your Changes
These are the integration tests that confirm that instant queries may
return stale NaNs when the query contains a rollup function.
The bug was reported at #5806. There is also a fix: #7275. The tests in
this PR will be used co confirm that the fix works.
Some test refactoring has been done along the way. Sorry, couldn't
resist.

### Describe Your Changes
As of right now by default aggregated output in streaming aggregation
takes a staleness interval and only starts sending first samples after
the staleness interval passes. We have a use case where we prefer to
start sending data as soon as we have any. This adds the option to
configure when we start sending first samples

### Describe Your Changes
1. **Add new `Raw Query` tab**
A new `Raw Query` tab has been added to the
[vmui](https://docs.victoriametrics.com/#vmui) interface for displaying
raw data. The tab uses the `/api/v1/export` API endpoint. Related issue:
[#7024](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7024)
2. **Fix rendering of isolated points on the graph**
Previously, isolated points (not connected to other points on the left
or right) were not visible on the graph. Now, they are rendered
correctly.

Previously, for `^` aka pow function calls, VictoriaMetrics returned `1`
if left arg was Nan. For example, given query=`(hour()==2)^1` returns 1
for NaN produced by hour() == 2 function. It added additional non-exist
datapoints to the timeseries.
This commit port bugfix from `metricql` package and adds test for it.
Now, VictoriaMetrics
correctly returns `NaN` for such cases.

Add the ability to create a simple cluster configuration for tests that
do not verify the cluster-specific behavior but instead are focused on
the business logic tests, such as API surface or MetricsQL. For such
tests this cluster configuration will be enough in most cases.
Cluster-specific tests should continue creating custom configurations.
