firewall: also configure VPN forwards in the app

There we can define forwards only for networks with actual VPN users.

Revert "firewall: configure NAT from NetBox data"
...
Changed my mind. All NAT and VPN is configured from the app now.

firewall: configure NAT from NetBox data
...
This is dynamic NAT for (mostly) physical networks. NAT for custom
prefixes can still be defined in the app.

Query prefixes once for all hosts
...
And group them into vrf_prefixes for VLAN networks and bgp_prefixes for
servers plugged directly into fabric.
This should reduce the number of queries to NetBox when configuring
firewalls and exit switches. Not sure but I think set_fact helps to
avoid queries (as opposed to setting group_vars).

exit: store VLAN interface addresses in NetBox
...
… instead of generating them from prefixes. A NetBox script can be
used to create and configure all necessary data for a new VLAN.
Instead of VLAN roles “inside" and “outside” we now create separate
VRFs for inside VLANs to match the actual exit/firewall configuration.
The “outside” VRF is for all VLANs that are directly accessible from
the internet.

firewall: accept VPN connections from inside also
...
People tend to leave WireGuard tunnels active and we don’t want things
to become unreachable when moving to one of the inside networks.

firewall: add known IP ranges in network ipset definitions

This data should only change in NetBox, so no point deploying it from
firewall master. Sometimes the first approach is the best approach.

Mostly to avoid special‐casing bond interfaces, and to support BGP

firewall: disable forwarding for mgmt interfaces in if-pre-up

Should be more robust and more importantly works when interfaces are
not renamed by mdev as is the situation now.

firewall: fix interface renaming

The mdev rules for renaming interfaces at boot seem to not work with
latest Alpine. So rename with ifupdown instead.
