Remove "System " prefix from default network manager profile names
Created by: jprorama
Default network profile naming in CentOS-7 NetworkManager uses the name 'System ethN' as the profile name for the 'ethN' interface. The ansible framework uses a single variable for the profile name interface name. We change the default profile names to match the interface name to match this convesion and make nmcli commands more consistent with tranditional naming.
