Deploying against servers on KVM with enp1s0 instead of eth0 fails. Eth0 seems to be hardcoded somewhere

[dwedia]

URL leads to a 404

Expected Behavior

I changed eth0 to enp1s0 in groupvars/all.yml.
Deployment should now run on my 3 target servers.

Current Behavior

The ansible playbook site.yml fails at this step:

Steps to Reproduce

1. changed flannel_iface: eth0 > flannel_iface: enp1s0
2. ran deployment playbook.
