Add authentication and authorization

[vityaman]

We want to use JWT for token based auth.

Also we need to think about theoretically supporting multiple login methods: Yandex ID, ITMO ID, Telegram (for bot).

@Kimiega, what do you think about using Yandex ID for authentication? It should be slightly more secure and trusted by users, than to store login and passwords here.

Do not forget to encrypt JWT payload. I did not this in LMS: vityaman-edu/lms#133

JWT Payload should be at least user_id, roles.

Our JWT token must support RFC8725.
