db integration for module configuration

[JonasNapierski]

• [x] create db model
• [x] user management
• [x] login tokens
• [ ] modules
  • [ ] load basic config inside db
  • [x] add module to db
• [ ] custom dockerfile

add db model includes support for loading all the necessary information inside the db from the module

removing usermanagment from this issues that is not the main goal.
