Brian Haley a0d1b0151a Delete OVS port on unstack to retain system connectivity
If you configure devstack with the following three values,
for example:

PHYSICAL_NETWORK=eth0
PUBLIC_INTERFACE=eth0
OVS_PHYSICAL_BRIDGE=br-eth0

This will cause devstack to create an OVS bridge, create a port for
eth0, and add it to the bridge (along with it's IP address).

The problem is that on unstack the port is never deleted from OVS,
so eth0 gets "trapped", not showing up in any of the OVS commands,
but not usable by the system.  The only workaround is to unload the
OVS kernel module.

There needs to be an 'ovs-vsctl del-port ...' call at the end of
_move_neutron_addresses_route() on unstack - the antidote to the
'ovs-vsctl add-port ...', that happened on stack.

Closes-Bug: #1516801

# or if using flat or VLAN provider networks, set in ``localrc`` to
# the name of the OVS bridge to use for the physical network. The
