Go - Sending traces, logs and metrics to the Victoria* stack

VictoriaMetrics now provides dedicated components for OTel signals: VictoriaMetrics for metrics, VictoriaLogs for logs, and VictoriaTraces for traces. The Go SDK communicates directly with these via OTLP/HTTP without requiring a collector, though each component uses distinct ports and paths. Implementation requires managing multiple OTel Go SDK modules and exporters. While metrics and logs are straightforward, configuring trace trees is more complex due to specific vocabulary and potential silent failures during the setup process.
