It seems there might be some redundancy between `os_info` and top level `host` field in telemetry message. Also [Host](https://github.com/DataDog/libdatadog/blob/dsn/crashtracker-errortracking-rfc/ddtelemetry/src/data/common.rs#L56-L70) structure definition does not appear to match exactly [definition](https://github.com/DataDog/dd-go/blob/prod/trace/apps/tracer-telemetry-intake/telemetry-payload/header.go#L24-L33) on backend side. _Originally posted by @nsavoire in https://github.com/DataDog/libdatadog/pull/554#discussion_r1793014113_
