roles/common: Add ipsets of abusive IPs to firewalld
...
This uses the ipsets feature of the Linux kernel to create lists of
IPs (though could be MACs, IP:port, etc) that we can block via the
existing firewalld zone we are already using. In my testing it works
on CentOS 7, Ubuntu 16.04, and Ubuntu 18.04.
The list of abusive IPs currently comes from HPC's systemd journal,
where I filtered for hosts that had attempted and failed to log in
over 100 times. The list is formatted with tidy, for example:
$ tidy -xml -iq -m -w 0 roles/common/files/abusers-ipv4.xml
See: https://firewalld.org/2015/12/ipset-support

roles/common: Add missing systemd-journald config

I apparently forgot to add this when I committed the systemd-journald
changes a few weeks ago.

One less thing to do manually after server provisioning, and there is
nothing sensitive in here anyways.

Both client and server support ed25519, so there's no need to even
have the RSA key here.
