The as_manager() method allows easy creation of chain-able managers. One
of the most common use cases for these is with related fields. However,
as_manager() doesn't currently allow use_for_related_fields to be
specified. This patch proposes it could be set simply by way of an
attribute on the QuerySet class, in the same way it currently does for
Manager classes.
