Summary:
Our descriptors currently have a method to return the name as it will be displayed on the elements hierarchy.
However, it doesn't provide enough context if the name is to be used to discover the type in our code base.
This change adds a qualified name method that can provide a more complete name which can indeed be used by the Open In IDE functionality, for example.
