Title:
  v2.0 fernet tokens audit ids are inconsistent

Status in OpenStack Identity (keystone):
  Fix Released
Status in OpenStack Security Advisory:
  Incomplete

Bug description:
  If you set the token provider to token.provider = fernet, get an
  unscoped token from v2.0, then rescope that token to a project, you'll
  notice the audit ids don't match. I've recreated this issue in a test
  [0].

  What should happen is that the unscoped token response will have a
  list of audit_ids containing a single audit_id. The project scoped
  token response from the unscoped token will also have a list of
  audit_ids in the token response but the original audit_id from the
  unscoped token will be in the list of the project scoped token.

  Right now this behavior doesn't exist in with the fernet provider on
  v2.0.
