docs: clarify multitenancy via labels for vmagent
Signed-off-by: hagen1778 <roman@victoriametrics.com>

Revert c6c5a5a186 and b2765c45d0
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.

follow-up for c6c5a5a186 ()
* adds datadog extensions for statsd:
  - multiple packed values (v1.1)
  - additional types distribution, histogram

* adds type check and append metric type to the labels with special tag
name `__statsd_metric_type__`. It simplifies streaming aggregation
config.

* remove statsd support from cluster, since cluster doesn't support
stream aggregation.

Feature allow configuring disableOnDiskQueue and dropSamplesOnOverload per url ()
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html):
allow configuring `-remoteWrite.disableOnDiskQueue` and
`-remoteWrite.dropSamplesOnOverload` cmd-line flags per each
`-remoteWrite.url`. See this [pull
request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6065).
Thanks to @rbizos for implementaion!
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): add
labels `path` and `url` to metrics
`vmagent_remotewrite_push_failures_total` and
`vmagent_remotewrite_samples_dropped_total`. Now number of failed pushes
and dropped samples can be tracked per `-remoteWrite.url`.

Statsd protocol compatibility ()
In this PR I added compatibility with [statsd
protocol](https://github.com/b/statsd_spec) with tags to be able to send
metrics directly from statsd clients to vmagent or directly to VM.
For example its compatible with
[statsd-instrument](https://github.com/Shopify/statsd-instrument) and
[dogstatsd-ruby](https://github.com/DataDog/dogstatsd-ruby) gems

docs: removed code-style highlighting for commanad-line flags of VM components ()
Using `sh` or `console` formatting doesn't do word-breaking on render. This makes flags description
harder to read, as users need to scroll the web page horizontally.
Removing the formatting renders the description with normal word-breaking.

app/vmagent: properly shutdown when -maxIngestionRate limit is reached
The remotewrite.Stop() expects that there are no pending calls to TryPush().
This means that the ingestionRateLimiter.Register() must be unblocked inside TryPush() when calling remotewrite.Stop().
Provide remotewrite.StopIngestionRateLimiter() function for unblocking the rate limiter before calling the remotewrite.Stop().

While at it, move the rate limiter into lib/ratelimiter package, since it has two users.
Also move the description of the feature to the correct place at docs/CHANGELOG.md.
Also cross-reference -remoteWrite.rateLimit and -maxIngestionRate command-line flags.

- Make the configuration more clear by accepting the list of ignored labels during sharding
  via a dedicated command-line flag - -remoteWrite.shardByURL.ignoreLabels.
