We should investigate and implement a way to inject Magnolia configurations in a cloud native way. E.g. through a AWS Systems Manager Parameter Store or similar mechanisms.

Points to consider:

• core properties such as `magnolia.resources.dir`, `magnolia.repo.home` etc (some of these are duplicated and re-defined in vitals webapp, which should be aligned).
• LDAP integration
• log4j configuration: Define log4j config file once for all environments/instances, e.g. custom log level/override vs. for 6 setups
• Repository configuration
• Testability
