IPv6 support for rhel distro

When the ubuntu networking info file has ipv6 addresses inside
it we need to make sure that we parse that information out and
place it (at least) in the rhel network configuration writing.

In later patches the other distros that use this parsed network
configuration will likely also need to be updated (ubuntu and
debian already should function as expected with regard to ipv6
support).
