Description yatanaka 2023-12-19 01:09:56 UTC 
Description of problem:

One of my customers is interested in using Heat to deploy octavia loadbalancers onto a specific availability zone.

Upstream Xena and later, we can use "availability_zone" parameter for OS::Octavia::LoadBalancer resource.

~~~
https://docs.openstack.org/heat/latest/template_guide/openstack.html#OS::Octavia::LoadBalancer-prop-availability_zone

- availability_zone
  Available since 17.0.0
  The availability zone of the Load Balancer.
  String value expected.
  Updates cause replacement.
~~~

However, "availability_zone" is not available in RHOSP 17.1 or Wallaby.
Could we backport "availability_zone" to RHOSP 17.1?

I suppose we need to backport the following change to implement "availability_zone" in RHOSP 17.1:
- https://github.com/openstack/heat/commit/ba0b6676c07e944ba046b2b067832e0583163662


Version-Release number of selected component (if applicable):
RHOSP 17.1


Actual results:
We cannot deploy loadbalancers onto a specific AZ using Heat.

Expected results:
We can deploy loadbalancers onto a specific AZ using Heat.
