Allow customized reseller_prefix in Ceilometer middleware for Swift

Browse Source 
Swift can be configured to use a different reseller prefix than AUTH_.
In this case Ceilometer returns None as resource_id.

This patch allows to set the reseller prefix, with a fallback to AUTH_
if not set. It also ensures that the reseller prefix ends with ``_``.
Two additional tests to verify this were added.
