Support for distributed traces

[alexbiehl]

It's very hard to know where a distributed-process application spends it's time. With something like OpenTracing or OpenTelemetry we have good tooling at our hands to analyse such traces.

We don't have to hard-code it down to OT or OTeL but supporting the concept of Traces, Spans and Links that would let a user plugin exporters might be a good way to integrate.
