-      - Supported options include 'state', 'commitment', 'trigger', 'target_free_space', 'delete_order', 'defer_delete',
-        'prefix', 'destroy_list'.
-      - All the above mentioned options except 'destroy_list' are supported in REST for ONTAP 9.13.1 or later with ONTAP collection version 22.8.0 or later.
-      - Option 'state' determines if the snapshot autodelete is currently enabled for the volume. Possible values are 'on' and 'off'.

-        Possible values are 'try', 'disrupt' and 'destroy'.
-      - Option 'trigger' determines the condition which starts the automatic deletion of snapshots.
-        Possible values are 'volume', 'snap_reserve' and DEPRECATED 'space_reserve'.
-      - Option 'target_free_space' determines when snapshot autodelete should stop deleting snapshots. Depending on the trigger,
-        snapshots are deleted till we reach the target free space percentage. Accepts int type.
-      - Option 'delete_order' determines if the oldest or newest snapshot is deleted first. Possible values are 'newest_first' and 'oldest_first'.
-      - Option 'defer_delete' determines which kind of snapshots to delete in the end. Possible values are 'scheduled', 'user_created',

-      - Option 'destroy_list' is a comma seperated list of services which can be destroyed if the snapshot backing that service is deleted.
-        For 7-mode, the possible values for this option are a combination of 'lun_clone', 'vol_clone', 'cifs_share', 'file_clone' or 'none'.
-        For cluster-mode, the possible values for this option are a combination of 'lun_clone,file_clone' (for LUN clone and/or file clone),
