Implement a Heat template for launching with a baremetal flavor using Ironic's nova baremetal launcher

Ironic does not necessarily have a l3 network. Once an Ironic node is operational, it must build its own network bsaed upon the DHCP adddresses it has been given. I think there is some hardware that supports OVS routing, but I am not clear on this point. The ultimate goal is to get a bay launching on bare metal so we get full baremetal network performance. This may mean connecting the bay's internal network with a Neutron l3 network. I'm just not sure, butI know the current router/port definitions used in the current heat template will not be useful for Ironic. When we use Ironic, we hvae to depend only on OS::Nova::Server as a resource type (with flavor set to baremetal).
