NEW case [different properties located at different places]

[showersky]

There is a quite interesting use case mentioned during the FIWARE TSC call to store the properties across different nodes in FogFlow for a single entity. This means, different properties of the same entity can be stored across multiple nodes, for example, part of properties on a cloud node and part of properties on an edge node. This is useful especially in an edge cloud environment. We will consider to support this in the future.
