Support for single interface Neutron networking with OVS

When running Neutron on a single node that only has a single interface,
the following operations are required:

    * Remove the IP address from the physical interface
    * Add the interface to the OVS physical bridge
    * Add the IP address from the physical interface to the OVS bridge
    * Update the routing table

The reverse is done on cleanup.

In order run Neutron on a single interface, the $PUBLIC_INTERFACE and
$OVS_PHYSICAL_BRIDGE variables must be set.
