Seems the conditional has changed and we should pickup the tripleo::profile::base::swift::storage::enable_swift_storage hiera data. After controller nodes are upgraded the swift services were down even though there was no stand-alone swift node (the current conditional was failing as that hiera isn't set any more) Closes-Bug: 1638821 Change-Id: Id1383c1e54f9cae13fd375e90da525230e5d23eb
