[Generator] use GOOGLE_CLOUD_CPP_ENABLE_TRACING to initialize tracing components #6185

While writing some examples for google/cloud/iam/ (they will help me understand credentials for the GUAC project) I discovered that GOOGLE_CLOUD_CPP_ENABLE_TRACING does not seem to work for generated clients. At a guess, the tracing components in google::cloud::Options is not getting initialized from the environment variable.

It looks like this was fixed by #8294, yes?

You are correct. Closing.
