[build][openstack] OpenStack stable branch deletion

Hi StarlingX Community, I’m reaching out to draw your attention to recent actions that the OpenStack community has been taking, as part of the stable branch processes. As part of this process, the following branches have reached end-of-life status, and therefore will be deleted: * stable/ussuri * stable/train Please read this email fro the OpenStack release team for more details: https://lists.openstack.org/archives/list/openstack-discuss@lists.openstack.... Thanks and Best Regards, Ildikó ——— Ildikó Váncsa Director of Community Open Infrastructure Foundation
