DAQInterface sometimes does not wait long enough for logfiles to appear
After starting the processes in an otsdaq-based system, I find that DAQInterface goes to the RECOVER state because it could not find the log file of one of the processes. A bit more debugging showed that the issue was related to the timing of the DAQInterface logfile check and the actual creation of the logfile; inserting a 5-second sleep was sufficient to ensure the file was found correctly.
It would probably be better for DAQInterface to retry within a certain timeout until all logfiles are found, and not just arbitrarily wait for some amount of time.

With the single-commit-branch bugfix/23564_wait_for_logfiles, it's now the case that if DAQInterface determines a logfile's missing, it'll wait two seconds and check again, doing this for a maximum of five checks.
