A new symlink is added to point to the latest log file, the symlink is in the same directory as the log files.

Behavior change:

Log file is rolled by max_log_file_bytes configuration (64MB by default) instead of the fixed line count, i.e. 200000.
Log files are named as log.<yyyyMMdd_hhmmss_SSS>, e.g. log.20240524_1806_235 instead of log.<index>.txt, e.g. log.123.txt
