Add the ancestor_slice dynamic table. This table given a slice ID finds all parents by following the chain of |parent_id| values. This is useful to allow queries to quickly find the parent of the given slice (imagine joining ancestor_slice(id) ON depth = 0). Bug: 160148605 Change-Id: I4a60b03a2f3fb8d6d2741fcc5b4c2217d70eb3fe
