Let's provide non-cookie based authentication.

### Main idea

For now, We mainly support login to Backend.AI Cluster via cookie `AIOHTTP` using webUI.When it comes to login from other sites (by clicking a button or sth else) that have different IP addresses,It's not possible to send the cookie to IP address that is connected to Backend.AI, which blocks the login procedure.In order to provide the DoF on our login process, we shall need to generalize the login process by supporting non-cookie-based authentication.
