Automatically backup and restore Swift rings from the undercloud
Swift rings created or updated on the overcloud nodes will now be stored on the undercloud at the end of the deployment. An additional consistency check is executed before storing them, ensuring all rings within the cluster are identical. These rings will be retrieved (before Puppet runs) by every node when an UPDATE is executed, and by doing this will be in a consistent state across the cluster. This makes it possible to add, remove or replace nodes in an existing cluster without manual operator interaction.
