Changing the default port-binding configuration

networking-odl no longer supports the network-topology port
binding controller and instead now relies on a pseudo-agent binding
controller.  This means that each OVS node must be configured with
host configuration in OVSDB about which VIF types, network types,
functions, etc that this OVS node supports.  The end result is this
affects where nova and neutron will schedule instances.

Changes Include:
 - Modifying default port binding controller to use pseudo agent
 - Adds necessary per role parameters to be able to configure host
   config on a per role basis to allow for heterogenous compute node
   configurations.
