title: get trace ID of sent request
body: <p>I'm using the Open Tracing Python library for GRPC and am trying to build off of the example script here: <a href="https://github.com/opentracing-contrib/python-grpc/blob/master/examples/trivial/trivial_client.py" rel="nofollow noreferrer">https://github.com/opentracing-contrib/python-grpc/blob/master/examples/trivial/trivial_client.py</a>.</p>
  
  <p>Once I have sent a request through the intercepted channel, how do I find the trace-id value for the request? I want to use this to look at the traced data in the Jaeger UI.</p>
