* Updated the storage_group_members table to add the 'storage_group_member_note' that can be set to 'DELETED' to track when a member is deleted. Updated anvil-version-changes to check for and add this column as needed. Updated the anvil.sql schema for the same.
* Updated Cluster->insert_or_update_storage_group_members to add the new column.
