Description of problem: After 24 hours of being up the auth_token_middleware attempts to retrieve the certificate_revocation_list but fails because the admin token is expired. There is no retry logic in this code path like there is with the uuid tokens to generate a new admin token. Fixed upstream. Backport patch on launchpad is here: https://review.openstack.org/#/c/23334/
https://review.openstack.org/#/c/23334/ Has been updated and now passes the tests. It should be considered a candidate for backport. It depends on the patch https://review.openstack.org/#/c/23468/1 which should also be backported.
