[EDP] Using trust delegation for Swift authentication

Registered by Michael McCune

For access to Swift objects, Sahara should be changed to generate a Keystone trust between the user with access to those objects and the Sahara admin user. The trust would be established based on the user’s membership in the project that contains the Swift objects. Using this trust the Sahara user could generate authentication tokens to access the Swift objects. When access is no longer needed the trust can be revoked thus invalidating the tokens.

With this methodology Sahara could move away from distributing the credentials for access and instead distribute tokens. In addition Sahara would not need to store tokens for long periods of time as they could be regenerated when needed.

(detailed spec in review)
