Improved performance in Sensors page

- The Sensors page takes too long to load, It is because we are
  trying to call the redfish endpoint: /Sensors' Members one by one
  and setting in the GUI. The change made is that we are using the
  query parameters' expand option to call only once and get all
  the required responses.

- We are using query parameters only for those which have MaxLevels>0,
  else calling the APIs one by one.

- Tested: Checked on a p10 system. For 306 records, it used to take
  1 minute 20 seconds, now takes 7 seconds to load.
