#### Why I did it - The xcvrd service requires an event detection function, unplug or plug in the transceiver. #### How I did it - Add sysfs interrupt to notify userspace app of external interrupt - Implement get_change_event() in chassis api. - Also begin installing Python 3 sonic-platform package for Celestica platforms
