As an outcome of tests with extensions introduced in Istanbul, Simplified CNF model, there is a need to add additional edge rules that will model new types of relations

generic-vnf-> generic-vnf (depends on)
vf-module -> vf-module (depends on)
k8s-resource -> k8s-resource (depends on)

The purpose is to optionally introduce these dependencies that will allow building Day-2 orchestration logic based on that. Later on, this information may be used to order proper deletion process in SO and can be used by (ext-)controllers to execute Day-2 operation in a certain order. These relationships should be created optionally - ideally from the SDC model. Here the scope is to enable these relationships in AAI
