sampleTrace(traceId: TraceId): Option[Boolean]
Should we sample this trace or not? Could be decided that a percentage of all traces will be let through for example.
Should we sample this trace or not? Could be decided that a percentage of all traces will be let through for example. True: keep it False: false throw the data away None: i'm going to defer making a decision on this to the child service

Tracer.SomeTrue and Tracer.SomeFalse as constant return values.

def
isActivelyTracing(traceId: TraceId): Boolean
Is this tracer actively tracing this traceId?
Is this tracer actively tracing this traceId?
Return: If TraceId.sampled == None sampleTrace() has not been called yet or the tracer still wants to receive traces but not make the decision for child services. In either case return true so that this tracer is still considered active for this traceId.
If TraceId.sampled == Some(decision) sampleTrace() has already been called, or a previous service has already made a decision whether to sample this trace or not. So respect that decision and return it.
