Adds configuration support for OpenDaylight SDN Controller

In order to use OpenDaylight with Neutron, ML2 must be configured to
point to the OpenDaylight controller instance.  It also requires the
networking-odl python library to drive communication with ODL.
Additionally each Open vSwitch instance must be configured to set the ODL
Controller as it's manager.
