We have introduced altering base_path for operations on resources. Volumes and Backups were not switched to this new method and were still relying on returning inherited classes VolumeDetail and BackupDetail. This change allow doing any supported operation on a resource returned by list immediately without any conversion or re-fetch. Change-Id: Ia095c53f1d04f1c119c6a6f8a38c5bfd60dc8a67
