NeCTAR Patches to Enable Host Aggregates and Availability Zones with Nova Cells

Since moving to nova-cells a few months back, we really wanted to still utilize host aggregates and availability zones.

Fortunately, we were able to piggyback off work NeCTAR had done to implement this functionality.  Here’s a list of patches we pulled in, and they’ve been working well.

A big thanks to the NeCTAR team, especially Sam Morrison, for all the help with this!
