[Backend] As a user, I can sign out

[nkhanh44]

Why

As users can sign in, the app must have an option for users to sign out. Signing out should completely remove any account-related footprints of the user.

Acceptance Criteria

Call POST /api/v1/oauth/revoke to sign out with the following body:

{
  "token": "{{user_access_token}}",
  "client_id": "{{client_id}}",
  "client_secret": "{{client_secret}}"
}
