The domain model(s) loaded into the system-modeller should be configured via an environment variable

It is good practice to have any configuration done through environment variables.

With the current set-up a user can put domain model(s) into the "knowledgebases" folder and this folder will be mounted by the system-modeller and any domain models within will be loaded on boot.

It would be better (and clearer) if we also had the ability to download a specified domain model(s) automatically based on an environment variable defined in .env (or wherever).

The solution we discussed is to create a custom entrypoint for the ssm container (as we have done for keycloak and nginx) so that the domain model(s) are downloaded first and then tomcat is started.

We could have a comma-separated list of domain model URLs in an environment variable.
