[Mellanox]PSU sensors dynamic configuration

[yuazhe]

Why I did it

Previously, the PSU sensor configuration inside sensors.conf is hardcoded for each platform, allowing no flexibility for other PSU combination possibilities. However, there exists a scenario that user has a second source of PSU which has different sensors compared to the original sensors.conf. Thereby it requires the system to have the ability to dynamically detect the PSU model in using and load relevant sensor’s configuration file.

Note: Run-time detect PSU changing and reload relevant sensor configurations is out of scope.

How I did it

This PR involves a new script and a corresponding data file which contains all PSU model’s sensor configuration info. The script reads the hardware PSU information through hw-management and determines its model. Based on that, it searches for the corresponding pre-defined PSU sensor data, integrate them into the sensors.conf, and let PMON copy it for further loading by lm-sensor.

How to verify it

use sensors command and check the psu section is rightly labeled.

LGTM but you are missing recent new device SN5400. Please add the relevant changes to this device as well

I have updated relevant changes according to SN5400 sensor configuration file.
