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
