Extend the Entity sensor MIB to include more sensors.
currently, Entity sensor MIB only include the SFP DOM sensors, in this extension, will add below sensors:

  1. the PSU voltage, current, power, temp
  2. Chassis fan speed, PSU fan speed
  3. Thermal sensors avalaible on the switch(ASIC, CPU, Ambt, etc.)

Looks good to me. @qiluo-msft to review from an SNMP perspective.

Extend RFC3433 implementation with:

1. FAN tachometers
2. PSU current sensor
3. PSU voltage sensor
4. PSU power sensor
5. PSU temp sensor
6. Chassis temp sensor

MIB HLD update PR to reflect this change please refer to: sonic-net/SONiC#766

A fix for the LGTM checker

**- How I did it**
1. Refactor sensor data parsing class by adding a base class  BaseSensorData;  inherit  TransceiverSensorData, PSUSensorData, FANSensorData, and ThermalSensorData from it to reduce redundant code.
2. Adding more sensor MIB entry class: PSUTempSensor, PSUVoltageSensor, PSUCurrentSensor, PSUPowerSensor, FANSpeedSensor, and ThermalSensor.
3. Separate MIB update to different functions according to different sensors types: update_xcvr_dom_data, update_psu_sensor_data, update_fan_sensor_data, and update_thermal_sensor_data.
4. Add unit test cases to cover the new added MIB entries.
5. Add lgtm.yaml to fix the LGTM checker.

**- How to verify it**

Manual test and run updated community SNMP test case(sonic-net/sonic-mgmt#3357).
