Firewall drivers check if port security is enabled. After ovo is sent
over the wire, the port_security_enabled is part of 'security' field.
The patch translates the RPC call from agent to server so the payload
containing port_security_enabled is at the same place.
We may consider implementing change of OVO field to contain boolean
directly.
