Cloned from launchpad blueprint https://blueprints.launchpad.net/nova/+spec/baremetal-availability-zones.

Description:

This feature is intended to provide availability zone support for the provisioning of baremetal nodes.  As with the current implementation, availability zones for a baremetal node lie on the compute node that is managing it.  For many environments this is insufficient as the ratio of compute nodes to baremetal nodes can be quite small.  Similarly, workloads that are well suited for baremetal provisioning typically call for segregation in the form of things like rack awareness.

This change would be comprised of an additional column within the baremetal database's bm_nodes table, the accompanying changes to the baremetal api/novaclient, and a new filter for nova scheduler.
