Migrate Swift ring handling from tripleo-heat-templates to puppet-tripleo

This allows decoupling the Swift ringbuilding logic from the Controller
and ObjectStorage roles. A follow up patch will modify
tripleo-heat-templates and use this modified class.

Actually this downloads the Swift rings even if ring building is
disabled or if there is no need to rebalance. This is required, because
operators can disable ring building, but use the same mechanism to
distribute pre-built rings to the nodes.

If ring building is disabled, these won't be uploaded at the end back to
the undercloud.
