client side http2 support?

See original GitHub issue

Hi~ great work!

Now i want to use grpc-web as the client side and grpc-java as the server side to make the rpc call, but after request code called, there were some error:

proto

syntax = "proto3";

option java_package = "com.xxx.xxxxxx.proto_out";


// The stream service definition.
service PlayStream {
    // Sends a greeting
    rpc PlayStreamGetInfo (StreamReq) returns (StreamAck) {}
}

// The request message containing the user's name.
message StreamReq {
    uint32 camera_id = 1;
}

// The response message containing the greetings
message StreamAck {
    uint32 camera_id = 1;
    string play_url = 2;
}

request (http)

let test_obj = new PlayStreamClient('http://localhost:9898', null, null);
            let request = new StreamReq();
            request.setCameraId(1);
            test_obj.playStreamGetInfo(request, {}, function(err, response){
                console.log(response);
            });

error

and then i change the request to https:

let test_obj = new PlayStreamClient('https://localhost:9898', null, null);

the errors:
