ups: check state on startup and update power status

Look for a UPS (uninterruptible power supply) D-Bus object on chassis
startup. If found, read its State and BatteryLevel properties to check
the condition of the power to the chassis. Update the CurrentPowerStatus
property hosted by the chassis state manager based on this information.

Tested:
- Utilized ibm-ups feature to start in debug mode so all properties
  could be manually set. Validated good path and bad paths for all
  properties and ensured CurrentPowerStatus was set as expected for each
  test.
