Public bug reported:

code at
https://github.com/openstack/nova/blob/master/nova/scheduler/filters/availability_zone_filter.py#L48
and
https://github.com/openstack/nova/blob/master/nova/tests/unit/scheduler/filters/test_availability_zone_filters.py#L40

shows we can support a list of AZs which is comma separated in one
aggregate.

but the azs is a string in metadata of aggregate, which
https://github.com/openstack/nova/blob/master/nova/scheduler/filters/availability_zone_filter.py#L48
is using 'in' operator.

solution is to:

form a list of azs from aggregate's metadata, and then use 'in'
operator.
