**Steps to reproduce.**
Follow instructions for trace integration.

**What is the expected behavior?**
Trace integration working

**What is the actual behavior?**
 trace_sampled=False Failed to integrate module: opencensus.ext.grpc.trace
No module named trace

**Additional context.**
Looking at other modules I see a trace.py.  Looks like grpc does not have one for now.

[reyang]

This seems to be a doc issue, the grpc integration is done by explicitly using the interceptors (refer to the examples) instead of through config_integration.

@allenjohnashton which instructions are you following? It'd help if you could post the code that gives you the error.

@c24t Sorry I did not update because @reyang was correct. The docs were incorrect. I see he has linked cl so I am assuming no further clarification was needed.
