NUT: Add sensor for computed power consumption

Describe the enhancement

Currently, the NUT integration exposes ups.load as the Load sensor, and ups.realpower.nominal (disabled by default) as the Nominal real power diagnostic sensor. Logically, I imagine other users like myself end up creating a template sensor to calculate power consumption from these two sensor values. Would it be possible to add a computed power consumption sensor which can be exposed by default if a UPS has both of these sensors? I'm not sure if this integration has any divergence from the explicit NUT server key/values, but this would be a nice simplification.

Use cases

Tracking power consumption is useful for a number of thing:

• power management and cost calculations
• checking power consumption deltas during shutdown sequences in the event of power failures

Anything else?
