Title: Decode body to array for OpenStack

Hi, im use Selectel (http://storage.selectel.ru) cloud with openstack swift (auth api v1.0), when i try to get_container, im got an error:

```
NoMethodError: undefined method `each' for #

Becouse selectel cloud send me `data.body` as string, not array

```
>> id.directories.get('awesome', :preffix => 'system')
