Kolla: Fetch network interface name from baremetal

network_interface and neutron_external_interface variables
are now fetched directly from the corresponding baremetal
nodes, so the hardcoding of them is removed.
These variables are now set in the inventory per host.

deploy-scenario: os-nosdn-nofeature
installer-type: kolla
