Implemented sensor class
Sensor class was introduced, it monitors
xyz.openbmc_project.Sensor.Value, for change and notifies all
listeners.
Tested:
- Unit tested with service stub that provides dbus interface
xyz.openbmc_project.Sensor.Value
- All changes are delivered to listeners
- All other unit tests are passing
