…r CMIS management (sonic-net#16955) - Why I did it When module is totally under software control, driver cannot get module temperature/temperature threshold from firmware. In this case, sonic needs to get temperature/temperature threshold from EEPROM. In this PR, a thread thermal updater is created to update module temperature/temperature threshold while software control is enabled. - How I did it Query ASIC temperature from SDK sysfs and update hw-management-tc periodically Query Module temperature from EEPROM and update hw-management-tc periodically - How to verify it Manual test New Unit tests

Backport PR: #16955
Why I did it
When module is totally under software control, driver cannot get module temperature/temperature threshold from firmware. In this case, sonic needs to get temperature/temperature threshold from EEPROM. In this PR, a thread thermal updater is created to update module temperature/temperature threshold while software control is enabled.
