This option determines the default availability zone for 'dmapi-compute'
services, which will be used if the service(s) do not belong to aggregates with
availability zone metadata.

Default availability zone for instances.

This option determines the default availability zone for instances, which will
be used when a user does not specify one when creating an instance. The
instance(s) will be bound to this availability zone for their lifetime.

Possible values:

* Any string representing an existing availability zone name.
* None, which means that the instance can move from one availability zone to
  another during its lifetime if it is moved from one compute node to another.
