Address rules by name instead of index. Still problematic if the rules
are changed while someone is managing them, but with names it’s
more likely to just not work instead of enabling or disabling the
wrong rule.
Also prevent bringing down the whole network with a single click.
I have tried every possible permutation and I think this is the one.
NetBox-managed IP prefixes are pushed with ansible to firewall master.
The managed prefixes are added to custom IP sets defined in the app,
but only NAT addresses and VPN groups can be configured for them.
This way all NAT and VPN policy is (again) configured in the app. Also
both NetBox-managed and user-defined networks are treated the same.
Also improve^Wtweak config generation. Also templates.
