Rename configuration variables and functions to reflect broader functionality beyond just log files. Updates include renaming LOG_DIRS_FOR_CLEANUP to DIRS_FOR_AUTODELETE and clean_log_files to clean_directory_files. Adds safety warnings to prevent deletion of critical HANA system logs. BREAKING CHANGE: Config keys renamed from LOG_DIRS_FOR_CLEANUP to DIRS_FOR_AUTODELETE and MAX_LOG_FILE_AGE_DAYS to MAX_FILE_AGE_DAYS
