Paramiko sftp client is not eventlet friendly. Also it doesn't work with some servers, so upload/download methods has been removed. Downloading or uploading can be done in other way (see examples). Added ability to pass process stdin, which makes possible to do on remote host anything at all. Much more clean and usable API. Change-Id: If357a2878c2c60646a975c386a0fe2f1616aec95
