When working with daemon, fixture started_daemon_worker will start daemon through circus and writing logs to the log file stay in the pytest tmp folder.
It is not straightforward to find where the log file is to check the daemon log that related to the hang engine tests.
The PR write a log in debug level to print the location of the daemon log.
