Add support for Glance Location API configuration in OpenStack operator

fmount · fmount · commit ea54d97262a5 · 2026-04-05T20:28:46.000+02:00
This change integrates the Glance Location API feature exposed by Glance.
It enables "single" GlanceAPI StatefulSet deployments with regular backends
for RHOSO 19, and it reduces the PVC resource requirements, resulting in a
simplified deployment topology.
The Location API is controlled via the "glance.openstack.org/location-api"
annotation in the Glance CR for backward compatibility, allowing existing
deployments to continue to work with the split method while enabling the new
single-API deployment model for new (19 based) setups.
