[orchdaemon]: Fixed sairedis record file rotation (#2299)

* [orchdaemon]: Fixed sairedis record file rotation * What I did Fix #8162 Moved sairedis record file rotation logic out of flush() to fix issue. Why I did it Sairedis record file was not releasing the file handle on rotation. This is because the file handle release was inside the flush() which was only being called if a select timeout was triggered. Moved the logic to its own function which is called in the start() loop. How I verified it Ran a script to fill log and verified that rotation was happening correctly. Signed-off-by: Bryan Crossland [email protected]
