NetworkManager/src/devices/nm-device.c
Thomas Haller cc1ee1d286 all: rework configuring route table support by adding "route-table" setting 
We added "ipv4.route-table-sync" and "ipv6.route-table-sync" to not change
behavior for users that configured policy routing outside of NetworkManager,
for example, via a dispatcher script. Users had to explicitly opt-in
for NetworkManager to fully manage all routing tables.

These settings were awkward. Replace them with new settings "ipv4.route-table"
and "ipv6.route-table". Note that this commit breaks API/ABI on the unstable
development branch by removing recently added API.

As before, a connection will have no route-table set by default. This
has the meaning that policy-routing is not enabled and only the main table
will be fully synced. Once the user sets a table, we recognize that and
NetworkManager manages all routing tables.

The new route-table setting has other important uses: analog to
"ipv4.route-metric", it is the default that applies to all routes.
Currently it only works for static routes, not DHCP, SLAAC,
default-route, etc. That will be implemented later.

For static routes, each route still can explicitly set a table, and
overwrite the per-connection setting in "ipv4.route-table" and
"ipv6.route-table".
