This PR adds the possibility to sign in via an OAuth 2.0 compatible identity provider (#171).

The database function login_with_extern and the utils function determineRoleByMapping are designed to hopefully be reusable by other external login providers added in the future.

Your code looks good, except for the most critical part: the actual login. I have also no clue how to test this code so it is difficult for me to actually verify that it is working correctly.

If you login with an external identity provider, you will note be able to also do password login? Why can't it be both? So that you set a password after doing a password reset in CTFNote and then you choose to use OAuth login or through your password and you enter the same account.
For example, we can initially set the password to null to prevent any authentication through password and ON CONFLICT here we just do nothing.

That is definitively an option (after dropping the NOT NULL constraint).
But in that case we would end up with the opposite situation: I have a local account and want to migrate it to external only. With that option, the best I can do is to choose a long, random password and immediately forget it. Since that is less impacting, I probably will change it that way in the upcoming days.
