**- Why I did it** - The thermalctld daemon on the Pmon docker requires support from the thermal manager API. **- How I did it** - Removed the old function for detecting a faulty fan. - Removed the old function for detecting excess temperature. - Implement thermal_manager APIs based on ThermalManagerBase - Implement thermal_conditions APIs based on ThermalPolicyConditionBase - Implement thermal_actions APIs based on ThermalPolicyActionBase - Implement thermal_info APIs based on ThermalPolicyInfoBase - Add thermal_policy.json
