d9e6c1d4dd
Adds a new model and provider for receipts which are very similar to tokens (fernet based), and share the same fernet mechanisms. Adds changes to the auth layer to handle the creation, validation, and consumptions of receipts as part of the auth process. Change-Id: Iccb6e6fc7aee57c58a53f90c1d671402b8efcdbb bp: mfa-auth-receipt
