Remove Ratpack dependency for HV-VES health checks
In order to minimize complexity and possibly improve performance (thread count) reactor-netty should be used instead of Ratpack. Also reorganize code to be more consistent and differentiated readiness and liveness endpoints (for future use in K8s Pod definition). As an example I've defined health check probe in docker-compose YAML.
