OAuth Support for new user signup

[charlesjliu]

Acceptance Criteria

• Mutation that supports creating users after connecting via OAuth only
• Use Passport for handling OAuth
• Refer to https://github.com/Coding-Coach/coding-coach-api for user sign up without OAuth

My suggestion on handling authorization and authentication would be to use a SAAS platform like: https://auth0.com/

Is anyone working on this?

Is this still open and available to be picked?
