Thomas Haller 5f54a323d1 route-manager: manage IPv4 device-routes with NMRouteManager 
When adding an IPv4 address, kernel will also add a device-route.
We don't want that route because it has the wrong metric. Instead,
we add our own route (with a different metric) and remove the
kernel-added one.

This could be avoided if kernel would support an IPv4 address flag
IFA_F_NOPREFIXROUTE like it does for IPv6 (see related bug rh#1221311).

One important thing is, that we want don't want to manage the
device-route on assumed devices. Note that this is correct behavior
if "assumed" means "do-not-touch".
If "assumed" means "seamlessly-takeover", then this is wrong.
Imagine we get a new DHCP address. In this case, we would not manage
the device-route on the assumed device. This cannot be fixed without
splitting unmanaged/assumed with related bug bgo 746440.
This is no regression as we would also not manage device-routes
for assumed devices previously.

We also don't want to remove the device-route if the user added
it externally. Note that here we behave wrongly too, because we
don't record externally added kernel routes in update_ip_config().
This still needs fixing.

Let IPv4 device-routes also be managed by NMRouteManager. NMRouteManager
has a list of all routes and can properly add, remove, and restore
the device route as needed.

One problem is, that the device-route does not get added immediately
with the address. It only appears some time later. This is solved
by NMRouteManager watching platform and if a matchin device-route shows up
within a short time after configuring  addresses, remove it.
If the route appears after the short timeout, assume they were added for
other reasons (e.g. by the user) and don't remove them.
