Add GitHub Oauth registration and login

[isabelcosta]

Description

As a developer,
I need to implement GitHub sign on,
so that I can allow GitHub users to login using their GitHub account.

For being able to use the application, the user has to create a new account and confirm the email just to login. It's a long process. So by having GitHub OAuth we can make the process shorter for users who have a GitHub account.

Acceptance Criteria

Update [Required]

• Implement GitHub OAuth login and registration
• Write unit tests for the updates ^^

Definition of Done

• All of the required items are completed.
• Approval by 1 mentor.

Estimation

8 hours

@isabelcosta Can I create an issue on the frontend also for this and start working on both as I will need the frontend to test the implementation from the backend?

[isabelcosta]

Yes, you can do that and build the feature full stack. Do create the issue and link to this comment of mine and to this issue. @codesankalp
