Subject: [PATCH] net/sysconfig: do not remove all existing settings of
/etc/sysconfig/network (#5991)
Reference:https://github.com/canonical/cloud-init/commit/fa331315d22f4bbe33320485e89a02bb2f695fbf
Conflict:use util.load_file not util.load_text_file in render_network_state().
In some distros, /etc/sysconfig/network may have important configurations that
are necessary for the instance to come up. For example, centos based distros
write NOZEROCONF=yes in /etc/sysconfig/network for some instances that require
zeroconf to be disabled. Removing these customizations would prevent the
instance to come up. So leave the customizations in /etc/sysconfig/network
intact except those that we are interested in.
Fixes GH-5990
