@bmridul can we have these in https://github.com/sonic-net/sonic-platform-common/blob/master/sonic_platform_base/sensor_base.py as the default implementation?

I looked into this, this would imply creating the private members of this implementation be put in the abstract base class. I think these are better left here.

@bmridul this part I am still not clear...why most of these APIs are not in base class given that it has nothing to do with FS implement or not

A file system based sensors implementation for Sensormond. Platforms can provide the sensor definition
in a file and Sensormond can use that to monitor the sensors.
HLD Reference: sonic-net/SONiC#1394
Description
Chassis base class looks for the presence of the file for sensors definition and uses that to built a list of sensor
objects if available.
Motivation and Context
See HLD mentioned above. This provides a simple implementation for platform support for Sensormond if the platforms have only Sysfs based sensors.
How Has This Been Tested?
Unit tested and tested on target.
root@sonic:/usr/local/etc# cat sensors.yaml

sensor: '/sys/bus/i2c/devices/23-0064/hwmon/hwmon49/in9_input'

low_thresholds: [ 2970, 3000, 3040 ]
