CoreOS does NOT configure network form configdrive network_data.json

Issue Report

Bug

We have on OpenStack network with disabled dhcp (static IP)
When we spin up a CoreOS VM we do not have IP configures as CoreOS
does not take it from config drive
When we start Ubuntu or CentOS VM with cloud-init we have everything in place and
networking working as intended.
