    public GrpcClientBuilder path(String prefix) {

Sets the context path for the gRPC endpoint.
This method will be useful if your gRPC service is bound to a context path.
For example:
<pre>{@code
// A gRPC service is bound to "/grpc/com.example.MyGrpcService/"
Server.builder()
      .serviceUnder("/grpc", GrpcService.builder()
                                        .addService(new MyGrpcService())
                                        .build())
      .build();

// Prefix "/grpc" to the gRPC service path.
GrpcClient.builder("https://api.example.com")
          .path("/grpc")
          .build(MyGrpcServiceGrpc.XXXStub.class)
}</pre>

@deprecated Use {@link #pathPrefix(String)} instead.
