The error appears when executing annotations query against Prometheus backend
because the query itself hasn't specified look-behind window (which is allowed
in VictoriaMetrics query engine).

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.

(cherry picked from commit 3661373cc2)
* 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.

Allocations are reduced by implementing custom json parser via fastjson
lib.
The change also re-uses `promInstant` object in attempt to reduce number
of
allocations when parsing big responses, as usually happens with heavy
recording rules.
```
name old allocs/op new allocs/op delta
ParsePrometheusResponse/Instant-10 9.65k ± 0% 5.60k ± 0% ~ (p=1.000 n=1+1)

it's needed to remove Summary metric type from the global state of
metrics package. metrics package tracks each bucket of summary and
periodically swaps old buckets with new.
Simple set unregister is not enough to release memory used by Set

(cherry picked from commit 6a6e34ab8e)
Change the return values for these functions - now they return the unmarshaled result plus
the size of the unmarshaled result in bytes, so the caller could re-slice the src for further unmarshaling.
This improves performance of these functions in hot loops of VictoriaLogs a bit.
Added `rate` and `rate_avg` output
Resource usage is the same as for increase output, tested on a benchmark
