[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 Co-authored-by: Stephen Sun <5379172+stephenxs@users.noreply.github.com>
