[Bug 1499000] [NEW] interfaces not brought up when ovs is started

[ben thielsen]

Public bug reported:

when ovs is started [e.g. systemctl start openvswitch-switch.service],
the services [ovsdb-server and ovs-vswitchd] are started, but no
interfaces are brought up.  running ifup --allow=ovs br0 manually after
ovs starts does bring up the interfaces.

>cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# bridge
#auto br0
allow-ovs br0
iface br0 inet manual
	ovs_type	OVSBridge
	ovs_ports	eth0 br0-host

# physical interface
#auto eth0
allow-br0 eth0
iface eth0 inet manual
	ovs_type	OVSPort
	ovs_bridge	br0

# internal interface [host os]
allow-br0 br0-host
iface br0-host inet static
	ovs_type	OVSIntPort
	ovs_bridge	br0
	ovs_options 	tag=681
	address		10.68.40.120/17
	gateway		10.68.60.1

additionally, stopping ovs stops the services, but the interfaces
remain.
