This change marks the iscsi deploy interface as deprecated and stops enabling it by default. An online data migration is provided for iscsi->direct, provided that: 1) the direct deploy is enabled, 2) image_download_source!=swift. The CI coverage for iscsi deploy is left only on standalone jobs. Story: #2008114 Task: #40830 Change-Id: I4a66401b24c49c705861e0745867b7fc706a7509
