Make auth_url lookup dynamic
If _get_auth_url() is run on heat-api startup, it can cause heat-api to crash in situations where Keystone is not running, yet or temporarily unavailable. This patch converts the auth_url attribute into a property method that is only run when it is needed, thus preventing this race condition.
