``storage_policies``
Storage policies determine on which hardware data is stored, how
the data is stored across that hardware, and in which region the
data resides. Each storage policy must have an unique ``name``
data resides. Each storage policy must have a unique ``name``
and a unique ``index``. There must be a storage policy with an
index of 0 in the ``swift.yml`` file to use any legacy containers
created before storage policies were instituted.
