Fix auth_token for old oslo.config

When running with a havana-level of oslo.config (<1.3.0),
applications with any config options in their api-paste.ini will
fail to start with an error like

 'StrOpt' object has no attribute 'type'

This is because the config options didn't have a type attribute
until 1.3.0.

During the grenade test, the havana level of oslo.config is used.
