Add support for "energy consumption" for AC

[Dimitris Zervas]

Describe the bug
I have a RAC_056905_WW-RAC (AC) (LG ArtCool Mirror) and the exposed sensors include "energy current" but I can't add it to the energy panel

Expected behavior
Be able to add the AC to the energy consumption of the house

The Energy dashboard supports energy (kWh) not power (watts) sensors - see Creating an Energy Sensor out of a Power Sensor.
