Port the Nova + Cinder Availability Zones scenario from the legacy openshift-ir-plugin / rhos-infrared automation into the shiftstack-qa stages. The AZ job installs OCP IPI on OpenStack with one Nova aggregate per compute host (one AZ each), OCP masters/workers distributed evenly across the AZs, and rootVolumes placed on per-AZ Cinder backends. Post- install verification asserts the OCP nodes and their root volumes landed in the expected Nova and Cinder AZs. Stages/roles: - prepare: configure_az.yml creates host aggregates + per-AZ volume types, configure_az_ceph_crush.yml pins each per-AZ pool to its host-local OSDs. - install: discovers Nova/Cinder AZs (tools_cluster_checks/discover_az.yml) and renders zones + per-AZ rootVolume types/zones into install-config. - verification: check_azs.yml verifies Nova and Cinder AZ placement. - day2ops: scaleup_worker and cinder_registry (AZ-aware registry storage). - cleanup: remove_az.yml tears down aggregates and AZ volume types, gated by az_remove_on_cleanup. - jobs_definitions/availability_zones_4.22_nightly.yaml wires it together. All AZ behaviour is gated behind az_enable / openshift_root_volumes (default false), so non-AZ jobs are unaffected.

Ports the Nova + Cinder Availability Zones scenario from the legacy
openshift-ir-plugin / rhos-infrared automation into the shiftstack-qa
stages, so it can run under ci-framework on RHOSO 18.
What it does
Installs OCP IPI on OpenStack with one Nova aggregate per compute host
(one AZ each), OCP masters/workers distributed evenly across the AZs, and
rootVolumes placed on per-AZ Cinder backends. Post-install verification
asserts the OCP nodes and their root volumes landed in the expected Nova
and Cinder AZs. Day2 coverage includes worker scaleup and an AZ-aware
integrated-registry test.
Changes
configure_az.yml(host aggregates + per-AZ volume types),configure_az_ceph_crush.yml(pins each per-AZ pool to its host-localOSDs).
