Create a self-signed CA, set up group configs, add script to allow new
connections through the firewall.
In the base debian role, drop the default nftables forward chain with
drop policy because it clashes with this. If you enable forwarding on
a debian host, make sure to configure the firewall.
Consolidate base system and networking setup into debian role and BGP
configuration into frr role. Add facts role to collect data from NetBox
once to avoid many slow lookups. Also many other tweaks and cleanups.
