add dev IF in ConfigServer for App

modify work flow between App && device, now activate/authorize/reset
must do by App by http request to MICOConfigServer.
1. modify http API in MICOConfigServer(TCP) for App:
add:        activate/authorize/reset/OTA;
remove:  read/write;
2. set device login_id/devPasswd just at Easylink config mode;
3. just transfer raw data between MCU <=> Cloud,  so MVDMsgProtocol is
not used;
4. no auto activate, must do by App.
