[Mellanox] Fix thermal control bugs (#4298) 
* [thermal control] Fix pmon docker stop issue on 3800
* [thermal fix] Fix QA test issue
* [thermal fix] change psu._get_power_available_status to psu.get_power_available_status
* [thermal fix] adjust log for PSU absence and power absence
* [thermal fix] add unit test for loading thermal policy file with duplicate conditions in different policies
* [thermal] fix fan.get_presence for non-removable SKU
* [thermal fix] fix issue: fan direction is based on drawer
* Fix issue: when fan is not present, should not read fan direction from sysfs but directly return N/A
* [thermal fix] add unit test for get_direction for absent FAN
* Unplugable PSU has no FAN, no need add a FAN object for this PSU
* Update submodules
