Adding support for fan_drawer class in PDDF common platform APIs #10213

Why I did it

  1. fan_drawer support was missing in PDDF common platform APIs. This resulted in 'thermalctld' not working and 'show platform fan' and 'show platfomr temperature' commands not working.
  2. _thermal_list array inside PSU class was not initialized. Made changes to attach the PSU related thermal sensors in the PSU instance.

How I did it

Added a common class pddf_fan_drawer.py. This class uses the PDDF JSON to fetch the platform specific data. A platform which uses PDDF would follow the below hierarchy.

fan_drawer_base.py ---> pddf_fan_drawer.py ---> fan_drawer.py

How to verify it

Run the 'show platform fan' and 'show platform temperature' commands and check the o/p.

[Accton/PDDF] Support show cmd for psu-temp and fan (#10215)
ab3053b 
Why I did it
Support for show platform temp/fan for psu-temp and fan.
Original code doesn't has fan_drawer to support these information.

How I did it
Support for show platform temp/fan for psu-temp and fan.
Add fan_drawer.py and update thermal.py to add needed code.
It need PDDF common code to support . (Refer to #10213)

How to verify it
Test show platform temp and show platform fan.
