+ Addresses failures when cleaning up orphaned openstack ports.
+ The main "openstack <object> list" command no longer accepts
+ the "-c created_at" option, which has been moved to a property
+ of the object and must now be queried with "openstack show object
+ UUID". Also, the created_at parameter sometimes returns "None"
+ instead of a timestamp, and the existing version of the script
+ does not catch this condition.
