relationships:
    # The relationship type here is to be used between service component nodes. What is achieved here is
    # functionality in providing this relationship information to the service components so that they can
    # do service discovery.
    #
    # This function will create/add to the rels list for components. So going from a "collector node -> analytics node"
    # for example, this is kind of the edge and will add:
    # 
    # ```
    # "collector_name:rel": ["analytics_name"]
    # ```
    #
    # To the key value store.
