Adds single NIC support for baremetal deployments

Simply use a new argument "-single_baremetal_nic <nic name>" to define which NIC to
bridge to on your host.  Also ensure when using this arg that your
ksgen_settings file has mac_address and private_mac as the same value
for your controllers (since you are using a single interface).
