Review comment:
It seems like the life cycle of a TraceContext is exactly one trace.
Thinking of such a circumstance that we have A, B, C three services and they
are inter-communicated through RPC like A->B->C, with both A and C mounted the
Agent while B not. Then, in the above situation, C will start a new trace since
the trace from A is stopped at B. Hence, C could not obsever A with the use of
TraceContext.
