Retrieve tenantid, storage_urls from authentication

These changes allow the API tests to retrieve Tenand Id (Project Id) and Storage URL information from the service catalog.

Modified the configuration values available.
If authentication is used, the API tests will authenticate to identity with the username and apikey provided.
From the service catalog, it will retrieve the tenant id.
The storage url will be determined by the type of url (internal or public) and the region provided (ORD, IAD, etc.)

X-Storage-URL will only be required when using the Swift Storage Driver; albeit this will be our primarily deployment scenario.

It will be required on all calls when it is required until we have decided on it will get injected (Repose, EOM Auth, other middleware, or a hook)
