[202012][202106] AS4630-54TE Support SystemHealthMonitor

[seanwu-ec]

Same content as #8183, but merge to branch 202012 and 202106

1. Implement FanDrawer-Fan hierarchy.
2. Enable thermalctld, disable pcied.
3. Implement SystemLED in Chassis.
4. Correct Fan direction
5. Implement require Fan APIs for SystemHealthMonitoring.
6. Handle non-ascii character while reading PSU model/serial num.

Why I did it

To support system health monitoring feature.

How I did it

Mainly provided a config file, system_health_monitoring_config.json. Then implement the SystemLED part that'd be manipulated by HealthChecker. Others are just to correct the provided information which will be utilized by HardwareChecker.

How to verify it

Check if System-health can pass the check and display the SystemLED correctly.

///////// booting, DIAG_LED = GREEN_BLINKING /////////

root@sonic:/tmp# show system-health detail 
System is currently booting...
root@sonic:/tmp# cat /sys/class/leds/diag/brightness

///////// container_checker fail, DIAG_LED = AMBER /////////
