Fixes LP #992096 - Add configure_via_auth=False

We now need to pass configure_via_auth=False to the glance
client constructor to signal that we don't want to have the
endpoint returned by the Keystone service catalog to override
the URL we are already passing in (the [image][host] configuration
option...)
