spyne client based on hierdoc serialization - json, msgpack, etc

[mtourne]

here is my application

    application = MySpyneApp([MySpyneRpc],
                                 tns='my.rpc',
                                 in_protocol=JsonDocument(validator='soft'),
                                 out_protocol=JsonDocument())

and the client that tries to use it :

        c = HttpClient("http://127.0.0.1:8001/", application)
        c.my_func("foo", "bar")

unfortunately the json that goes out is :

{"message": "foo", "op": "bar"}

when it should be :

curl http://127.0.0.1:8001/ -d '{ "my_func" : { "message" : "foo", "op": "SIGN_ADMINAUTHTOKEN" } }' 

I've poked around a bit in the code and it looks like up until about here [1], the whole thing is contained neatly in request_raw.
