Recent versions of Keystone require auth tokens when accessing the
/v3/s3tokens endpoint to prevent exposure of a lot of information that
a user who just has a presigned URL should not be able to see.
UpgradeImpact
=============
The s3token middleware now requires Keystone auth credentials to be
configured. If secret_cache_duration is enabled, these credentials
should already be configured. Without these credentials, Keystone users
will no longer be able to make S3 API requests.
