You've already forked prometheus-fail2ban-exporter
							
							Add a basic systemd service file to serve as an example on how to run the exporter as a system service. Add short README with an overview of the service file.
Systemd
The .service file in this directory should be copied to the /etc/systemd/system/ folder.
- It expects the binary file to be installed at 
/usr/sbin/fail2ban_exporter. - It expects a user named 
fail2ban_exporterto exist. This user should not have a shell or any special privileges aside from read-access to the fail2ban socket file. 
The ExecStart line can be modified to add any custom CLI flags.
