produced samples by aggregation rule, previously it was overcounted, and

Consistently using t.Fatal* simplifies the test code and makes it less fragile, since it is common error
to forget to make proper cleanup after t.Error* call. Also t.Error* calls do not provide any practical
benefits when some tests fail. They just clutter test output with additional noise information,
which do not help in fixing failing tests most of the time.

### Describe Your Changes
Implement spellcheck command:
- add cspell configuration files
- dockerize spellchecking process
- add Makefile targets
This PR adds a standalone `make spellcheck` target to check `docs/*.md` files for spelling
errors. The target process is dockerized to be run in a separate npm environment.
Some `docs/` typo fixes also included.

### Describe Your Changes
In most cases histograms are exposed in sorted manner with lower buckets
being first. This means that during scraping buckets with lower bounds
have higher chance of being updated earlier than upper ones.
Previously, values were propagated from upper to lower bounds, which
means that in most cases that would produce results higher than expected
once all buckets will become updated.
Propagating from upper bound effectively limits highest value of
histogram to the value of previous scrape. Once the data will become
consistent in the subsequent evaluation this causes spikes in the
result.
Changing propagation to be from lower to higher buckets reduces value
spikes in most cases due to nature of the original inconsistency.
See: https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4580
An example histogram with previous(red) and updated(blue) versions:
This also makes logic of filling nan values with lower buckets values: [1 2 3 nan nan nan] => [1 2 3 3 3 3] obsolete.
Since buckets are now fixed from lower ones to upper this happens in the main loop, so there is no need in a second one.

(cherry picked from commit 1c155a0cd1)
vmbackup, vmrestore and vmbackupmanager use the same libs
for integrations with object storage. That means the auth can be configured
in the same way for all of them. So the docs should have either identical
config section for all 3 components, or we should cross-link to one source of truth.
This change removes incomplete auth options from vmrestore docs and adds link
to complete auth options in vmbackup instead.

### Describe Your Changes
These changes support using Azure Managed Identity for the `vmbackup`
utility. It adds two new environment variables:
* `AZURE_USE_DEFAULT_CREDENTIAL`: Instructs the `vmbackup` utility to
build a connection using the [Azure Default
Credential](https://pkg.go.dev/github.com/Azure/azure-sdk-for-go/sdk/azidentity@v1.5.2#NewDefaultAzureCredential)
mode. This causes the Azure SDK to check for a variety of environment
variables to try and make a connection. By default, it tries to use
managed identity if that is set up.
This will close

### Testing
However you normally test the `vmbackup` utility using Azure Blob should
continue to work without any changes. The set up for that is environment
specific and not listed out here.
Once regression testing has been done you can set up [Azure Managed
Identity](https://learn.microsoft.com/en-us/entra/identity/managed-identities-azure-resources/overview)
so your resource (AKS, VM, etc), can use that credential method. Once it
is set up, update your environment variables according to the updated
documentation.
I added unit tests to the `FS.Init` function, then made my changes, then
updated the unit tests to capture the new branches.
I tested this in our environment, but with SAS token auth and managed
identity and it works as expected.

(cherry picked from commit 5fd3aef549)
'any' type is supported starting from Go1.18. Let's consistently use it
instead of 'interface{}' type across the code base, since `any` is easier to read than 'interface{}'.
This makes easier to read and debug these tests. This also reduces test lines count by 15% from 3K to 2.5K .
See https://itnext.io/f-tests-as-a-replacement-for-table-driven-tests-in-go-8814a8b19e9e .
While at it, consistently use t.Fatal* instead of t.Error*, since t.Error* usually leads
to more complicated and fragile tests, while it doesn't bring any practical benefits over t.Fatal*.
The logo on the README is hard to recognize in dark mode on GitHub, so I
made it responsive based on user preferences.

### Describe Your Changes
This PR is aimed to change the currently in place configuration of
running Go related jobs for code changes that don't contain actual Go
files ([example
1](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6517/checks)
- 2m32s , [example
2](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6543/checks)
- 4m11s).
In order to do that the `build` workflow was extracted from Go related
workflow (now it doesn't require lint as a `need` step -- let me know if
it's something we want to keep). It will run upon the same triggers as
before the change.
The `main` workflow now will be triggered by `**.go` pattern only and
contains lint/test steps that are relevant for Go file changes.
I expect this PR +
https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6540 to improve
CI minutes usage.

(cherry picked from commit c429bbf889)
Reason for revert:
There are many statsd servers exist:
- https://github.com/statsd/statsd - classical statsd server
- https://docs.datadoghq.com/developers/dogstatsd/ - statsd server from DataDog built into DatDog Agent ( https://docs.datadoghq.com/agent/ )
- https://github.com/avito-tech/bioyino - high-performance statsd server
- https://github.com/atlassian/gostatsd - statsd server in Go
- https://github.com/prometheus/statsd_exporter - statsd server, which exposes the aggregated data as Prometheus metrics
These servers can be used for efficient aggregating of statsd data and sending it to VictoriaMetrics
according to https://docs.victoriametrics.com/#how-to-send-data-from-graphite-compatible-agents-such-as-statsd (
the https://github.com/prometheus/statsd_exporter can be scraped as usual Prometheus target
according to https://docs.victoriametrics.com/#how-to-scrape-prometheus-exporters-such-as-node-exporter ).
Adding support for statsd data ingestion protocol into VictoriaMetrics makes sense only if it provides
significant advantages over the existing statsd servers, while has no significant drawbacks comparing
to existing statsd servers.
The main advantage of statsd server built into VictoriaMetrics and vmagent - getting rid of additional statsd server.
The main drawback is non-trivial and inconvenient streaming aggregation configs, which must be used for the ingested statsd metrics (
see https://docs.victoriametrics.com/stream-aggregation/ ). These configs are incompatible with the configs for standalone statsd servers.
So you need to manually translate configs of the used statsd server to stream aggregation configs when migrating
from standalone statsd server to statsd server built into VictoriaMetrics (or vmagent).
Another important drawback is that it is very easy to shoot yourself in the foot when using built-in statsd server
with the -statsd.disableAggregationEnforcement command-line flag or with improperly configured streaming aggregation.
In this case the ingested statsd metrics will be stored to VictoriaMetrics as is without any aggregation.
This may result in high CPU usage during data ingestion, high disk space usage for storing all the unaggregated
statsd metrics and high CPU usage during querying, since all the unaggregated metrics must be read, unpacked and processed
during querying.
P.S. Built-in statsd server can be added to VictoriaMetrics and vmagent after figuring out more ergonomic
specialized configuration for aggregating of statsd metrics. The main requirements for this configuration:
- easy to write, read and update (ideally it should work out of the box for most cases without additional configuration)
- hard to misconfigure (e.g. hard to shoot yourself in the foot)
It would be great if this configuration will be compatible with the configuration of the most widely used statsd server.
In the mean time it is recommended continue using external statsd server.
