Add kWh as cost option for gas (#58426)

Browse Source 
* Add kWh as cost option for GAS

* Add kWh as cost option for GAS (pylint)

* Add kWh as cost option for GAS (make CONST)

* Change GAS_UNITS to VALID_ENERGY_UNITS

* Add test for Gas cost in kWh (2)

* Back off ENERGY_WATT_HOUR - unlikely for gas

* Add MEGA_WATT_HOUR support (2)

* Normalise pricing for MEGA_WATT_HOUR

* Normalise pricing for MEGA_WATT_HOUR
