Swift supports storage policies for a long time, making it possible to
store specific objects on different devices[1].
This patch adds a second storage policy to support testing API features
that rely on storage policies, eg. per-policy quotas[2]. There are no
additional Swift devices created and the existing ones are re-used to
keep the overhead to the minimum.
