Kener uses sqlite by default but also installs mariadb and postgres

[jakobrosenberg]

By default Kener is configured for sqlite (DATABASE_URL=sqlite://./database/kener.sqlite.db), yet it also installs two separate database services.

This seems like a case of extreme and unnecessary bloat that could be handled through one of the following options:

1. Comment out services and env variables that aren't used
2. Refer to official documentation
3. Create separate templates
