Fix log rotation issue

Writing log to a single file from multiple processes is not supported
by python logging. It causes making fragmented log files at log
rotation and logs are mixed up.

This change is to use different log files for each sub-process
to help developers check log for a specific process easily.
This change does not affect to pod log (stdout log).
