Handling custom files if removed from list

[sradco]

In other roles we remove the files relevant for the role in case they where removed from the logging_output_list or in case rsyslog_enabled is false.

What do we want to do if a custom file that was deployed to /etc/rsyslog.d was removed from the list or in case rsyslog_enabled is false?
