Title: Fixing debian_ip.py per #14530.

Updating the template used by the debian_ip module to configure the /etc/network/interfaces file to ensure that ipv4 options are only included when they are configured. Currently if ipv6 only networking is configured then the interfaces file ends up in a malformed state. Per #14530.
