* [vmagent] added ingestion rate limiting with new flag `-maxIngestionRate`. This flag can be used to limit the number of samples ingested by vmagent per second. If the limit is exceeded, the ingestion rate will be throttled.

When `--vm-native-step-interval` is specified, explore phase will be executed
within specified intervals. Discovered metric names will be associated with
time intervals at which they were discovered. This suppose to reduce number
of requests vmctl makes per metric name since it will skip time intervals
when metric name didn't exist.
This should also reduce probability of exceeding complexity limits
for number of selected series in one request during explore phase.

It is assumed that URLPrefix.busOriginal will be initialized
durin Unmarshal of the config. But in tests we set fields manually,
so this field never get initialized properly.
Fixes the error `panic: runtime error: integer divide by zero`
at `vmauth.getLeastLoadedBackendURL`.

(cherry picked from commit 83a8c24281)
The `match[]` filter is mandatory at /api/v1/series, so it mustn't be dropped here.
There is no sense in dropping `match[]` filter together with `extra_label` and `extra_filters[]`
at /api/v1/labels and /api/v1/label/.../values if -search.ignoreExtraFiltersAtLabelsAPI commnad-line flag is set,
since:
- the `match[]` filter triggers slow path at these APIs;
- the `extra_label` and `extra_filters[]` filters narrow down the number of matched time series,
so they improve performance comparing to the case when only `match[]` filter is left,
while `extra_label` and `extra_filters[]` filters are dropped.
This is a follow-up for 0b7a23a91d
Improved trace display for better visual separation of branches:
* Increased left padding for each element
* Added padding for the last element in the branch
For example, if `interval: 1m`, then data flush occurs at the end of every minute,
while `interval: 1h` leads to data flush at the end of every hour.
Add `no_align_flush_to_interval` option, which can be used for disabling the alignment.
The match[] at /api/v1/labels and /api/v1/label/.../values also may lead to slow requests and
high resource usage if it matches big number of time series. So it must be igrnored if -search.ignoreExtraFiltersAtLabelsAPI
command-line flag is set.

* app/{vmagent,vminsert}: adds /v1/metrics suffix for opentelemetry route path
it must fix compatibility with opentemetry-collector [spec](https://opentelemetry.io/docs/specs/otlp/\#otlphttp-request)
this suffix is hard-coded and cannot be changed with collector configuration
* Apply suggestions from code review

- Document the ability to read OpenTelemetry data from Amazon Firehose at docs/CHANGELOG.md
- Simplify parsing Firehose data. There is no need in trying to optimize the parsing with fastjson
and byte slice tricks, since OpenTelemetry protocol is really slooow because of over-engineering.
It is better to write clear code for better maintanability in the future.
- Move Firehose parser from /lib/protoparser/firehose to lib/protoparser/opentelemetry/firehose,
since it is used only by opentelemetry parser.

Prevsiously they were swapped - the first arg should be the label name and the second arg should be label filters
