gRPC OpenTracing to OpenCensus Adapter

This adapter injects an OpenCensus span in the metadata of a gRPC call, which is extracted from your OpenTracing span before.

If your project uses OpenTracing and you call a service via gRPC, which uses OpenCensus, this adapter makes the span available in the remote service.

d, err := grpc.Dial("localhost:9080", grpc.WithInsecure(),
    grpc.WithUnaryInterceptor(otocadapter.OpenCensusAdapterClientInterceptor(tracer)),
)
if err != nil {
    logrus.Fatalln("Can't connect to DGraph:", err)
}
defer func() {
    d.Close()
    logrus.Info("Closed Dgraph connection...")
}()
dgraphClient := dgo.NewDgraphClient(api.NewDgraphClient(d))
