[test_operator][wntp] Add controller IP config to each tempest step

The test_operator role already adds a value for the tempest.conf param
`whitebox_neutron_plugin_options.proxy_host_address`, but it only does
this at the generic `tempestconfRun` parameter.
That `tempestconfRun` can be overriden per tempest step, using the
`workflow` list from the tempest CR.
This patch adds the value for
`whitebox_neutron_plugin_options.proxy_host_address` to each workflow
step.
