DO NOT MERGE ANYWHERE Add new interface for sensor physical data 



This is special solution only for emerald branch.

Changes including new const char* value/interface for sensor physical data. Sensor service and manager does not take care of content, structure or other
details of string. Sensor HAL is taking care of parsing data from string and setting values to Sensor HW.
