Public bug reported:
An empty-named AZ can be set using the following command if there exists an
aggregate 'foo':
$nova aggregate-set-metadata foo availability_zone=
+----+------+-------------------+---------+----------------------+
| Id | Name | Availability Zone | Hosts | Metadata |
+----+------+-------------------+---------+----------------------+
| 55 | foo | | 'node2' | 'availability_zone=' |
+----+------+-------------------+---------+----------------------+
This empty-named AZ is meaningless and confusing, because it ISN'T the default
AZ. For example if we list AZ there will be an empty entry:
$nova availability-zone-list
+-----------------------+----------------------------------------+
| Name | Status |
+-----------------------+----------------------------------------+
| internal | available |
| |- node1 | |
| | |- nova-conductor | enabled :-) 2015-12-07T08:15:49.000000 |
| | |- nova-consoleauth | enabled :-) 2015-12-07T08:15:50.000000 |

| nova | available |
| |- node3 | |
| | |- nova-compute | enabled :-) 2015-12-07T08:15:50.000000 |
+-----------------------+----------------------------------------+
However, nova scheduler CANNOT distinguish between this empty-named AZ and the
default AZ, for example:
$nova boot --flavor 42 --image <image> --availability-zone "" test
The scheduler will treat "" as default AZ, the 'test' instance will be booted
in either "" or the default "nova" AZ.
