Created Course Selling App 2 (used JWT)

Same as the Course_Selling_App_1 project, but in this project I have used JWT for authentication.

I have introduced the sign-in endpoints for both users and admins.

For this one, in every authenticated requests, one needs to send the JWT in headers (Authorization : "Bearer {actual_token}").

I have used MongoDb to store all the data persistently.
