User Managment

[michael-fuchs]

Figure out how the user management, authentication and authorization should work.

Ideally deferred to some OpenID connect service like Azure (what we have for everybody).

Questions to be decided:

• What user data has to be stored in the blog's DB?
• What are the required roles? (Admin, Author, Anonymous, more?)
• Should we start with OpenId right away, or better with something more simple?
• If we use OpenId, which should be the first authentication provider? Keycloak? Azure-AD? Github? Google?
  It should be one that all fumiX developers can use right away, but is ideally also usable with OS in mind, i.e. others can install the app and can use it without too much hassle.
