Download elastisys-pom-root JAR file with all dependencies

Elastisys root pom. Specializations need to specify a ${docker.registry} property for the targeted docker registry (e.g. 'index.docker.io/v1/' or 'my.private.registry:5000') and may want to specify a template for the ${docker.repo} property (such as '${docker.registry}/${docker.image}' for a private registry or just '${docker.image}' when using docker hub).
