docs: Inserts a hierarchy (tree) of entries into the DIT. The hierarchy is passed as a list. The order of the entries
  in the list is important. Throws {@link MissingParentException} if an ancestor of some entry is missing. In
  particular this will happen if the list is not ordered properly. If the root entry (=first) already exists, an
  {@link EntryAlreadyExistsException} is thrown. Note that this action is not atomic.
