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

0587841476 roles/nginx: Adjust certbot tasks
It seems that it is no longer recommended/supported to install the
standalone certbot-auto client on Ubuntu 20.04. We apparently need
to use the one provided by Ubuntu, which luckily includes a service
and timer to renew the certs.

ba3004ef2b roles/common: Don't run rc.local task on Ubuntu 20.04
We haven't actually used rc.local since Ubuntu 16.04. Now anything
that we need to run at boot we can do with systemd anyways.

ef6ce2335e roles/common: Remove systemd-journald drop-in
Older Ubuntus originally didn't use a persistent journal, which was
somewhat of a surprise when looking at logs after a few months. Now
this does not seem to be an issue since Ubuntu 18.04. As for CentOS
I do not use that distro here so I don't need to care.

96f62a17d1 roles/common: Use nftables backend in firewalld on Ubuntu 20.04
The nftables backend should be more performant and flexible. I had
been planning to use it on Ubuntu 18.04 and Debian 10 as well, but
there were issues with the specific versions used in those distros.

set via firewalld.

roles/common: Use iptables backend for firewalld on Debian
For some reason the nftables set support in firewalld doesn't seem
to be working. I see that sets (aka ipsets in nftables lingo) are
created, but they are empty. For now I will just leave these tasks
as they are to revert the behavior on current hosts (should do no
change on new installed, as the regexp won't match).
