This adds a request filter that, if enabled, allows us to use placement to select hosts in the desired availability zone by looking up the uuid of the associated host aggregate and using that in our query for allocation candidates. The deployer needs the same sort of mirrored aggregate setup as the tenant filter, and documentation is added here to make that clear.

The scheduler can now use placement to more efficiently query for hosts within
|
|
an availability zone. This requires that a host aggregate is created in nova
|
|
with the ``availability_zone`` key set, and the same aggregate is created in
|
|
placement with an identical UUID. The
|
|
``[scheduler]/query_placement_for_availability_zone`` config option enables
|
|
this behavior and, if enabled, eliminates the need for the
|
|
``AvailabilityZoneFilter`` to be enabled. |
