Redfish: Enhance and fix power/thermal sensors

Made the following enhancements for Redfish power/thermal sensors:
* Now dynamically obtains the DBus object path to pass to
  GetManagedObjects() when getting sensor values.  Was previously
  hard-coded to "/" which didn't work on some systems.
* Added "fan_tach" to list of DBus sensor types returned when thermal
  sensors are requested.
* Added support for one-chassis systems.

Made the following fixes:
* Fixed @odata.id value when power sensors are requested.  Previously
  returned "/redfish/v1/Chassis/chassis/Thermal".
* Renamed "PowerSupply" to "PowerSupplies" to conform to schema.
* Removed 6 properties that were being returned for PowerSupplies that
  were not in the schema.
* Added check to make sure no sensors of the wrong type were being
  returned.  Previously if the same connection (service) provided both power
  and thermal sensors, both types of sensors were always returned.

Test Plan:
  https://gist.github.com/smccarney/79186e8510ba5479e846f2592d44d059

Tested: Verified the URLs /redfish/v1/Chassis/<chassis>/Power and
        /redfish/v1/Chassis/<chassis>/Thermal return the correct sensor
        names and values on a Witherspoon system.  Verified fixes listed
        above worked.  Ran Redfish Service Validator.
