* 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. --------- Signed-off-by: hagen1778 <roman@victoriametrics.com> Co-authored-by: hagen1778 <roman@victoriametrics.com>
