Ensure LXD veth host device is named correctly

LXD uses a veth pair to plumb the LXD instance into the bridge
providing access to neutron networking.

In later nova-lxd versions, the host_name parameter is set based
on the neutron configured name for the host part of the pair,
ensuring that neutron iptables firewall rules are correctly
applied to instances.

Update the mitaka version of the driver to populate the LXD
network device configuration to ensure that any firewall
rules are correctly applied.

(also dropped version from setup.cfg, as pbr will automatically
generate the version based on git tags, so its really surplus
to requirements).
