Code Issues Proposed changes

Set IPV6_AUTOCONF=no on initial onboot devices 

This commit sets IPV6_AUTOCONF=no from the anaconda installer for
all interfaces that are enabled during the initial install.

Once the puppet manifest is applied, and it updates the networking
config scripts for the system, this will be overwritten by that config,
which disables it for all configured interfaces,

IPv6 auto-configuration is causing an issue during backup and restore,
where router advertisements are causing the default route to be deleted,
which causes the calico pod to fail to initialize.
