Pre-release v5.0.0-rc10

• Cleanup
  • Removed unused structure in the auth package
  • Updated some documentation in the fsutil package
• Reworked the auth package
  • Authenticators depend on a UserService instead of executing DB query themselves
  • Encourage using user DTO instead of models
  • This all results in removing a dependency between presentation and data layer
  • Removed FindColumns. The "username" and "password" fields are not marked with struct tags anymore: they are handled by a repository.
  • Reduced (but not eliminated) uses of reflection. Now only the password field from the DTO returned by the user service is retrieved using reflection.
  • Take advantage of generics even more
  • The request's context is now properly propagated by JWT and basic authenticators
