[device/celestica]: Update DX010 platform APIS on 201911 branch (#5416)
* [device/celestica]: DX010 platform API update (#4608)

- Fix fancontrol.service path
- Fix return temp format in thermal API
- Improve init time in chassis API
- Upgrade sfp API

* [device/celestica]: Update DX010 reboot cause API (#4678)

- Add more cases support in DX010 reboot cause API
    - Add Thermal Overload reboot cause support
    - Add new Watchdog reboot cause support

* [device/celestica]: using sonic-py-common package
