Save answer POST request

[alodahl]

This depends on #72 so work on that first if you're interested and it isn't already assigned.

Add a new POST endpoint for the route: /user/answers/question/{questionNumber}

In the body of the request, include the necessary attributes (see #72) to save.

(Until auth is implemented, you can use guest as the user_id. Just make sure the record exists so the foreign key constraint isn't violated.)

In the main.js browser JavaScript, please submit an AJAX request (using fetch) to the above endpoint for any correct answer from the user. We can ignore incorrect answers for now.

This data will be retrieved in #96 if you're interested in working on that part.

@josselineperdomo I've assigned you so you can get started but keep in mind to get this fully working, you'll need #72 to be merged so just keep that in mind 😃
