All:

For the proposed zones / distributed scheduler functionality <https://blueprints.launchpad.net/nova/+spec/zones101>, can we defines  zones that overlap without being nested? 

Consider the scenario where: 

* We have two datacenters: one in Arlington, Virginia (ARL), and one in Marina del Rey, California (MDR).
* At each datacenter, we have both conventional x86 nodes and  nodes with GPUs 

Can we define our zones such that:

* We have a zone for each datacenter (ARL, MDR)
* We have a zone for GPU nodes  (GPU)

In this case, the GPU zone would both overlap the ARL and MDR zones, but ARL and MDR would not be fully nested within GPU.
