The install file resulted in creating /etc/default/networking/ as a
directory and installing the networking.default file in it. Rename
networking.default to networking, and change the install file.
Normally dh_installinit handles all this, but since the package is
ifupdown2, and the file is networking, that doesn't happen.
Also, because we had created a directory with the name of what we want
to install as a file, we need to remove it if it exists. This addition
of a preinst file should not go upstream, and should be removed in a few
weeks when everybody has re-installed enough.

jessie's networking starts as an init.d service. Trying to force ordering
between init.d and systemd services when there are dependencies doesn't work
well (especially since the init.d/networking service is forced very early
because of the remote filesystem requirement in jesie).
Converting networking to a script run as a systemd service allows us to start
networking after switchd. The new script is /sbin/start-networking. I chose
to keep it in /sbin, rather than put it in /usr/cumulus/bin, because it's core
functionaity.
I am not removing /etc/init.d/networking, it just gets ignored unless somebody
types it manually. If somebody does that, systemctl runs through the lsb
hooks. The two lost abilities below are just ignored if passed. I'm
also preventing creating the rc.d symlinks to the init.d/networking
script to reduce future confusion.
We lose some init.d "convenience" functionality because it's not available
through systemd. What we lose are:
reload-currently-up - can still be done with ifreload --currently-up
force-reload - can still be done with ifreload -f -a
We keep start, stop, reload, restart
These include changes that were done to move ifupdown2
to use pybuild and some debian policy fixes
