Added test to test sensor monitoring

Verify the Redfish sensor monitoring by an expected sensor table.
Tester need to prepare a python file as below.
An example table of expected sensors:
     redfish_sensor_info_map = {
       ${OPENBMC_MODEL}:{
           "Voltage":{
               "Voltage0",
               ...
           },
           "Temperature":{
               "DIMM0",
               ...
           }
           "Fans":{
               "Fan0",
               ...
           }...
       }
    }
