Bug 976907

Description of problem:
The foreman installer uses a reference to an openstack host's nic rather than its own secondary interface when creating a subnet.  This causes subnet creation to fail.

Version-Release number of selected component (if applicable):


How reproducible:
If the nic name on the openstack host differs from the one used as the secondary host on the foreman installer (very likely).

Steps to Reproduce:
1.  Run foreman_server.sh where PRIVATE_INTERFACE is not an active network interface.
2.
3.

Actual results:
The OpenStack default subnets and provisioning templates fail to get installed due to a ruby stack trace.

Expected results:
No failures after installing.

Additional info:
After adding --verbose and --trace to the rake task, here is the line that causes the error in foreman_server.sh.

+ sudo -u foreman scl enable ruby193 'cd /opt/rh/ruby193/root/usr/share/foreman; rake --verbose --trace db:seed RAILS_ENV=production FOREMAN_PROVISIONING=true'
