Timotej Lazar d123db4e64 Consolidate NAT and VPN settings into IP sets
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.

Timotej Lazar cac7658566 Fix handling default settings
If a setting has ben set to empty string, dict.get will return it and
not default argument. This is wrong when default is something else.

Timotej Lazar d33fec65a2 system: support LDAP queries with no user_group set
Though it might be better to allow multiple groups. On the other hand
the main filter is in the group→ipset settings file anyway; any VPN
user not in one of those groups will not get forwarded to anywhere.

Timotej Lazar c3e35777e0 Do not configure prefixes defined in NetBox
Push them to firewall nodes with ansible instead, as they will only
change in NetBox. Also don’t mess around with ipset “groups” based on
hyphenation, which was probably a bad idea.

With more data included in NetBox I am thinking we should configure
NAT and other stuff with ansible also, but let’s start small.

Timotej Lazar a8abf580f9 vpn: assign an IPv6 subnet instead of a single address
We are limited by the size of IPv4 pool (/18), so why not give
everyone an IPv4-internetful of IPv6 addresses.

Timotej Lazar 22cec64bef Simplify database locking
Use a single lock for everything to ensure we don’t go inconsistent.
One exception is the firewall nodes table which is only accessed when
pushing updated config.
