to load the interface driver. This patch allows it to load
interface driver via stevedore aliases.

The metering agent iptables driver can now load its interface driver by
using a stevedore alias in the ``metering_agent.ini`` file. For example,
``interface_driver = openvswitch`` instead of
``interface_driver = neutron.agent.linux.interface.OVSInterfaceDriver``
