The variable _base_url was not really necessary since we are setting up the endpoint_override variable which will eventually be used when making a request through the keystoneclient's session. This is a step in getting the client to use the keystoneclient's API more wisely. A subsequent CR will remove the need for the endpoint_override and make use of keystoneclient's endpoint_filters to discover the Barbican endpoint.
