ANSI color codes in zm-testagent.out

[PolaricEntropy]

I'm installing zm-testagent as a daemon service on Ubuntu 22.04 LTS by following the instructions, specifically this section: https://doc.zonemaster.net/latest/installation/zonemaster-backend.html#4-installation-on-debian-and-ubuntu

This sets up zm-testagent as a daemon service with the following command line perl /usr/local/bin/zonemaster_backend_testagent --logfile=/var/log/zonemaster/zm-testagent.log --outfile=/var/log/zonemaster/zm-testagent.out --pidfile=/var/run/zonemaster/zm-testagent.pid --user=zonemaster --group=zonemaster start

When the service starts successfully, zm-testagent.out is empty. However, if I introduce an error by making a typo in backend_config.ini to the database connection string, in that case, I get content in the zm-testagent.out file with color codes zonemaster-testagent �[32m[Started]�[0m.
I'm not sure if these color codes are by design or if it's possible to turn them off.

It is worth noting that /var/log/zonemaster/zm-testagent.log produces error messages that it cannot connect to the database.

@PolaricEntropy, thank you for the report. I do not think it is the desired behavior. Let us see if we can get rid of it.
