`model-server` start helper

This 'component' is not a real component but rather a start helper - the model-server is started using the Gradle application plugin.

To start the model-server, simply call the following in the repository root:

./gradlew model-server:run --args="-inmemory -dumpin courses.modelserver.dump"

As an alternative, you can also use Docker to run an in instance of model-server using the following command:

docker run  --rm -p 28101:28101 -d modelix/modelix-model:1.3.2 java -XX:MaxRAMPercentage=85 -Djdbc.url=$jdbc_url -cp "model-server/build/libs/*" org.modelix.model.server.Main -inmemory
