    Remove cache invalidation when using expired token

    This can create a race condition for long running services that reuse
    their token (eg. Kubernetes Cinder CSI plugin) in this case for
    example:

    1 [user] Asks nova to attach a volume to a server
    2 ...the user's token expires
    3 [user] Asks cinder if the volume has been attached
    4 [nova] Asks cinder to attach the volume

    In step 3 the token is marked as invalid in the cache and step 4 fails
    even if allow_expired is true
