Ifupdown2 is now setting a default metric on macvlan ips. This policy will let
users disable this new default behavior. addressvirtual_with_route_metric is
boolean policy variable.
addressvirtual_with_route_metric: yes|no|on|off|1|0 (default to yes)
$ cat /var/lib/ifupdown2/policy.d/addressvirtual.json
{
"addressvirtual": {
"module_globals": {
"addressvirtual_with_route_metric": "no"
}
}
}

Now that some system support ip addr METRIC sets we dont have to do this
"fix_connected_route" hack. The hack was previously introduced to make
sure the primary address was the first in the routing table. Some events
could cause some issues like having the macvlan address first in the
routing table. In that case the macvlan needs to be flapped. This shouldn't
happen when we are able to set the address metric

This is a major update coming all at once from master-next branch
master-next branch was started with --orphan option which is basically a new
branch without history.
The major changes are:
- repackaging
- cleanup the directory tree
- rewritte setup.py to allow install from deb file or pypi (pip install)
- add a Makefile to make things (like building a deb) easier
- review all debian files

ifupdown2 code was one level deeper because ifupdown2 initially
had ifupdown2 and ifupdown2-addons as two separate packages.
Since they were combined into one package, it makes sense to
move all combined code under the top level directory
