We have two paddlecloud directories; are they duplicated?

[wangkuiyi]

A Go source file directory https://github.com/PaddlePaddle/cloud/tree/develop/go/cmd/paddlecloud, and a Python one https://github.com/PaddlePaddle/cloud/tree/develop/paddlecloud.

[typhoonzero]

The go source file directory containing a go command line client for users to communicate to paddlecloud server.

The python code contains paddlecloud server side which parses user's command line commands and interacts with kubernetes api server to do "real" job creation and termination.

We'll remove the paddlecloud directory once the new client under paddlectl is ready.
