Code review comment for ~raharper/cloud-init:fix/sysconfig-skip-resolvconf-no-dns-config

It can be argued that cloud-init *was* doing the right thing.
It was told that there were no dns servers and no dns 'search' (by lack of that in network config).

dhcp muddies that argument for sure.

That said, based on the content in the description of the bug (the
previously-existing /etc/resolv.conf), cloud-init should *never* be
writing that file when 'netconfig' is involved. It seems rather that
resolv.conf is generated based on contents of
/etc/sysconfig/network/config .

Would writing /etc/sysconfig/network/config with valid content for NETCONFIG_DNS_STATIC_SEARCHLIST and friends fix this?
