app/{vminsert,vmagent}: preliminary support for /api/v2/series ingestion from new versions of DataDog Agent
This commit adds only JSON support - https://docs.datadoghq.com/api/latest/metrics/#submit-metrics , while recent versions of DataDog Agent send data to /api/v2/series in undocumented Protobuf format. The support for this format will be added later. Thanks to @AndrewChubatiuk for the initial implementation at https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5094 Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4451

Extra labels may be added to all the written time series by passing `extra_label=name=value` query args.
|

For example, `/datadog/api/v1/series?extra_label=foo=bar` would add `{foo="bar"}` label to all the ingested metrics.

For example, `/datadog/api/v2/series?extra_label=foo=bar` would add `{foo="bar"}` label to all the ingested metrics.

DataDog agent sends the [configured tags](https://docs.datadoghq.com/getting_started/tagging/) to
