Issue multi-tenant/expanded options for Amazon S3 backup.

[Robin Rae]

Question/issue:
(after having early awaited this extension)
when selecting the Openstack comaptible option for the extension, I'm missing a number of common (and required in my environment) fields:

notably and especially: tenantName

what I expect from openstack swift are the following fields:

username
tenant
api_key
password
bucket
authurl
autocreate (not required, default: true)
region (not required)
use_snet (not required, default: false)
cache_timeout (not required, default: 600)
verify_ssl (not required, default: true)

can someone shed light on this? or is this a feature request?
