roles/common: create /etc/apt/keyrings
According the the Debian docs for third-party repositories we must
create this manually on distros before Debian 12 and Ubuntu 22.04.
This is due to changes in apt-secure and the deprecation of apt-key.

roles: don't compare literal true and false
I changed these yesterday when editing the truthy values, but acco-
rding to ansible-link we can just rely on them being true or false
without comparing.

roles: strict truthy values
According to Ansible we can use yes, true, True, "or any quoted st-
ring" for a boolean true, but ansible-lint wants us to use either
true or false.

roles/common: Update list of abusive IP addresses
This comes from the AbuseIPDB with a confidence level of 95%. I use
the following command to download and sort the IPs:

  $ curl -G https://api.abuseipdb.com/api/v2/blacklist -d \
    confidenceMinimum=95 -H "Key: $ABUSEIPDB_API_KEY" \
    -H "Accept: text/plain" | sort | sed -e '/:/w /tmp/ipv6.txt' \
    -e '/:/d' > /tmp/ipv4.txt

I manually add the XML formatting to each file and run them through
tidy:

  $ tidy -xml -utf8 -m -iq -w 0 roles/common/files/abusers-ipv4.xml
  $ tidy -xml -utf8 -m -iq -w 0 roles/common/files/abusers-ipv6.xml

Then I formatted the nftables files manually. Meh...

roles/common: use pyinotify backend for nginx fail2ban jail
This seems to be automatically selected, but on some other servers
I notice it is not. I will set it here explicitly so fail2ban does
not fall back to the inefficient "polling" or incorrect "systemd"
backends.

roles/common: Disable unsafe Diffie-Hellman SSH moduli
The WeakDH team showed (in 2015) that Diffie-Hellman key exchange
with prime number groups of 1024 bits or less were weaker than we
previously thought, and well within the reach of nation states. They
recommended (in 2015) using 2048-bit or higher prime groups.

The SSH audit project recommends that we should use 3072-bit now.

roles/common: notify fail2ban after updating firewall
We should always restart fail2ban after updating the firewall. Also
note that the order of execution of handlers depends on how they are
defined in the handler config, not on the order they are listed in
the task's notify statement.

Note: there were no IPv6 addresses in the top 10,000 this time so I
used a dummy address for the nftables set so the syntax was valid.

roles/nginx: minor rework of acme.sh tasks
After the inital acme.sh script is downloaded and bootstrapped we
can remove it. If a host already has been bootstrapped then there
is no need to download it and do it over again.

roles/nginx: generate snakeoil cert manually
The ssl-cert does this, but it includes the hostname of the server
as the subject name in the cert, which is a huge leak of privacy.
