Optional "comment" in config name
When the directory that contains the configuration files for the different backup tools has multiple configurations for the same tool it gets nearly impossible to figure out what the configurations do without looking into the file. This can be solved with adding an optional input field to the finish function of the different helpers which makes it possible to add a custom "comment" to your configurations to identify them later quickly. This input field has to validate for this pattern "0-9a-zA-Z_-" because points in the file name confuse backupninja which handler to call onto the configuration.
For example:
90-hourly-full-mariabackup.borg
91-daily-file-backup.borg
