Reformat auth_url based on the ID API version.

No longer raising an OSCredsError when the auth_url does
not end with a 'v' + some number. Additionally, the auth_url
will be massaged to remove any 'v' + num from the end of
the URL and generate its own version value based on the ID
API version configured.
