availability_zone was not updated on time

[Guangya Liu (Jay Lau)]

Step 1) Create an aggregate
root@liugya-ubuntu:~# nova aggregate-create agg1 nova
+----+------+-------------------+-------+---------------------------------+
| Id | Name | Availability Zone | Hosts | Metadata |
+----+------+-------------------+-------+---------------------------------+
| 1 | agg1 | nova | [] | {u'availability_zone': u'nova'} |
+----+------+-------------------+-------+---------------------------------+
root@liugya-ubuntu:~# nova aggregate-add-host 1 liugya-ubuntu
Aggregate 1 has been successfully updated.
+----+------+-------------------+--------------------+---------------------------------+
| Id | Name | Availability Zone | Hosts | Metadata |
+----+------+-------------------+--------------------+---------------------------------+
| 1 | agg1 | nova | [u'liugya-ubuntu'] | {u'availability_zone': u'nova'} |
+----+------+-------------------+--------------------+---------------------------------+
root@liugya-ubuntu:~# nova aggregate-list
+----+------+-------------------+
| Id | Name | Availability Zone |
+----+------+-------------------+
| 1 | agg1 | nova |
+----+------+-------------------+

Step 2) Update aggregate
root@liugya-ubuntu:~# nova aggregate-update 1 agg1 nova1
Aggregate 1 has been successfully updated.
+----+------+-------------------+--------------------+----------------------------------+
| Id | Name | Availability Zone | Hosts | Metadata |
+----+------+-------------------+--------------------+----------------------------------+
| 1 | agg1 | nova1 | [u'liugya-ubuntu'] | {u'availability_zone': u'nova1'} |
+----+------+-------------------+--------------------+----------------------------------+
root@liugya-ubuntu:~# nova aggregate-list
+----+------+-------------------+
| Id | Name | Availability Zone |
+----+------+-------------------+
| 1 | agg1 | nova1 |
+----+------+-------------------+

Step 3) Boot one instance

    Update availability_zone on time if it was changed

    The problem is that when the availability_zones for one host
    aggregation was updated, the VM attribute of availability_zones
    which belong to the host in the availability_zones was
    not updated on time.

    If updated values include availability_zones, then the cache
    which stored availability_zones and host need to be reset.

    Fix bug 1203250
