    Expand relationship support to memberspecs

    As the title say, this expand the relationship support to memberspecs, i.e. 
if a memberspec has a DSL pointing to any other entity, it will now display an 
arrow to it.
    
    Here is how it looks like:

    And this done with the classic 3 tier webapp blueprint:
    ```yaml
    name: My Web Cluster
    services:
