Monitoring Template having incomplete custom definition

The monitoring ELK template, https://github.com/openstack/heat-translator/blob/master/translator/toscalib/tests/data/tosca_elk.yaml, is having nodes that are using input variables for interfaces but the related custom definition is missing it.

The app_collectd node template defines the Configure operation of the Standard interface. Specifically, it defines an implementation but it also assigns a value to the “logstash_ip” input. However, the interface definition does not define a “logstash_ip” input.
· similarly, the kibana node template defines the Configure operation of the Standard interface. Specifically, it defines an implementation but it also assigns a value to the “kibana_ip” and “elasticsearch_ip” inputs. However, the interface definition does not define a “kibana_ip” or “elasticsearch_ip” input.
· Same problem with the app_rsyslog node template. It assigns a value to an undefined “logstash_ip” input.
· Same problem with the mongo_dbms node template. It assigns a value to an undefined mongodb_ip input
