roles/common: Add mosh ports to common
These have been in each hosts's "extra" rules lists forever and I
use them on every single host so they might as well be in the base
rules.

roles/common: Use AbuseIPDB.com list in nftables
For now I am still manually updating this, as we can only hit their
API five times per day, so it is not possible to have each host get
the list themselves every day with our one API key.

roles/common: Use Abuse.ch's SSL Blacklist in nftables
This adds Abuse.sh's list of IPs using blacklisted SSL certificates
to nftables. These IPs are high confidence indicators of compromise
and we should not route them. The list is updated daily by a systemd
timer.

See: https://sslbl.abuse.ch/blacklist/

roles/common: Port configurable firewall logic to nftables
This opens TCP port 22 on all hosts, TCP ports 80 and 443 on hosts
in the web group, and allows configuration of "extra" rules in the
host or group vars.

roles/common: Add initial support for nftables on Debian 11
I will try using nftables directly instead of via firewalld as of
Debian 11 as it is the replacement for the iptables/ipset stack in
recent years and is easier to work with.

This also includes a systemd service, timer, and script to update
the spamhaus DROP lists as nftables sets.

Still need to add fail2ban support.
