This adds publishing of artifacts to AFS in parallel with the existing
publishing to the static volume.
The additional tasks added to the openstack-artifacts.yaml playbook
have been tested in the project-config-test-artifacts-to-afs test
(results at [1]) and also in an external project
ironic-python-agent-builder (see notes in [2]). Thus we can have high
confidence it will work.
After this merges, I will manually rsync the old static tarballs data
to the AFS directory (again; it has been sync'd previously) and from
that point on both should be exactly the same.
At that point we can switch the DNS entries for
static.<openstack|opendev>.org (the sites have been created with [3])
to the new server and we will be fully migrated to the AFS volume. We
can then remove the static publishing.
