      Description

      HDDS-2939 makes fundamental changes to how OM writes & reads its metadata. Since this is about as big a layout change as can be, we have to make sure this is properly managed through the upgrade flow. In addition to upgrades, we should support downgrades from pre-finalized state of OM.
