[ravi11o]

Implement user's login and signup using JWT authentication

Each user must have

• email(unique)
• name
• username(unique)
• password

Optional fields are

• image
• bio

Upon successful registration/login on the server end, client must receive a JWT token.
The JWT token should be encoded using user's ObjectId, username and email.

You must design endpoints for signup, login, current-user and profile fetch/update on your own.
