CloudForms inventory fails when an openstack cinder volume contains no 'device' directive in the attachments property

Issue

• CloudForms inventory fails when an openstack cinder volume contains no 'device' directive in the attachments property.

MariaDB [cinder]> select mountpoint from volumes where id='a97eeccd-7f99-4038-9fd4-8fe8db61c26a';
+------------+
| mountpoint |
+------------+
| NULL       |
+------------+

• To workaround this we can add a mountpoint to the offending cinder volume

MariaDB [cinder]> update volumes set mountpoint='/dev/vda' where id='a97eeccd-7f99-4038-9fd4-8fe8db61c26a';
