Enables tracing with OpenTelemetry
Setting this option enables the generation of traces by the client library. The library uses the global tracer provider to generate traces.
Prerequisites
The library must be compiled with OpenTelemetry in order for this option to take effect.

Effect
Setting this option enables the generation of traces by the client library. The library uses the global tracer provider to generate traces.
Exporting traces
Providing this option to a client only enables the generation of traces. It does not enable the export of traces.
In order to export the traces, the application must set the global tracer provider. The client library recommends using #google::cloud::otel::ConfigureBasicTracing() to configure the global tracer provider. This will send the traces generated by the client library to Cloud Trace, Google Cloud's visualizer for distributed traces.

Environment variable
This option is controlled by the GOOGLE_CLOUD_CPP_OPENTELEMETRY_TRACING environment variable. If the environment variable is set to a non-empty value, tracing with OpenTelemetry is enabled.
