deprecation: Drop support for systemd older than 232.

[SuperQ]

I think we should deprecate systemd support for versions older than 232. This would cleanup a bunch of if statements in service templates and eliminate the use of ansible_facts.packages in many of the roles. This would allow us to remove the python-apt/python3-apt package install from

This would mean we would set the minimum support matrix:

• Debian 9
• Ubuntu 18.04
• RHEL/CentOS 8

CentOS 7 is EOL in June 2024, so I think that's going to be the last supported distro we will need to drop first.
