In some cases, the logrotate is not fast enough rotating the logfile after sighub has been send to inputfilegen process. It appears to happen more often on github CI machines, when it happens, inputfilegen reopens the NOT yet rotated file and keeps writing into it. However most messages written until the next sighub are lost after the logfile finally is rotated. In order to avoid this, I have added an extra sleep between file CLOSE and OPEN after sighub with a default of 5ms which appears to work very well. This should give logrotate enough time to perform the actuzal rotate. Also added another parameter to inputfilegen to keep the process open after finish. Which helps syncing with the testcases. closes: https://github.com/rsyslog/rsyslog/issues/5000
