Is your feature request related to a problem? Please describe.
try to use open source tracer tool for llm performance, but not supported.

Describe the solution you'd like
as now dify already supported langfuse and other tools for llm monitoring.
Please consider adding support for OpenTelemetry trace exporting via OTLP (either gRPC or HTTP), ideally:

Respect existing OTEL_EXPORTER_OTLP_ENDPOINT, OTEL_SERVICE_NAME, OTEL_SAMPLING_RATE, etc.
Use the official Go OpenTelemetry SDK (go.opentelemetry.io/otel)
Optionally continue supporting Langfuse in parallel

Describe alternatives you've considered
