xenserver: allow dom0 traffic in secure pool host when controller unavailable.
A pool configured for secure fail-mode can block dom0 traffic on hosts joining
the pool or if the host reboots while the controller is unavailable. This
commit sets default flows on a host under these conditions to allow management
traffic. Once the connection with the controller is re-established, these
default flows are replaced by the controller.
