All contrail vrouter interfaces are down. Unknown cause

[Sudhir Kumar]

The vrouter interfaces page shows all interfaces as down.
I don't know of any cause that resulted in this state; but I had rebooted the server a few days back.

'contrail-schema' seems to have gone to a failed state ; but I am not sure if that is the reason for the interfaces to be down.
Will attach the contrail-schema logs (just in case).
